Horner APG HE693CALKIT simulation module

Horner APG HE693CALKIT simulation module

Product Introduction

（1） Product Features

Horner APG HE693CALKIT calibration software is a computer program designed to support on-site and factory calibration of specific Horner APG simulation modules.

（2） Package composition

Each set includes: a floppy disk with calibration software, an RS-232 9-pin serial cable, a TTL to RS-232 converter, and an RS-232 ribbon cable with a 10 pin plug.

（3） Software operation requirements

Operating environment: Requires running on an IBM or compatible computer using DOS 3.1 or higher.

Hardware requirements: A text display is required and a serial port (COM1 or COM2) is used. The program defaults to using COM1.

（4） Module connection and preparation

The simulation module needs to be connected to the selected serial port on the computer through an RS-232 cable, combined with a TTL-to-RS-232 converter or an RS-232 ribbon cable with a 10 pin plug (depending on the simulation module to be calibrated).

The module does not need to be configured in the PLC, but appropriate power must be provided for the bus pins of the module.

Set conditions

（1） General Requirements (2.1)

Module installation: The module to be calibrated must be inserted into the PLC it will be used in the application; When inserting, the PLC must be powered off. After the module is correctly inserted into the PLC rack, the rack should be installed vertically (see Figure 1) to ensure good ventilation of the module; The PLC must be in 'stop' mode.

Stabilization time: After inserting the module into the PLC and completing the calibration connection, it needs to stabilize for at least 15 minutes after power on to ensure appropriate temperature balance.

Environmental requirements: Do not expose any equipment involved in the module or calibration process to extreme temperature changes; Calibration can be performed using an expansion rack.

（2） Set up process (2.2)

No additional special steps are required, and it should be carried out in conjunction with equipment preparation and module specific conditions.

（3） Equipment Requirements (2.3)

Calibrator: High quality calibrators (such as Omega CL511) must be used, and their accuracy must be more than twice that of the module (for example, THM884 has an accuracy of ± 1 degree Celsius, and the calibrator accuracy must be at least ± 0.5 degrees Celsius); It is recommended that all Horner Electric simulation modules use battery powered calibrators. When calibrating any thermocouple module, a battery powered calibrator must be used.

Wire requirements: The wire used for calibration must be the same as the wire used in the application, and must be of high quality with the shortest possible length; Avoid exposing wires to excessive radio frequency (RF) or electromagnetic interference (EMI) during the calibration process to prevent introducing errors.

（4） Module specific conditions (2.4)

1. Analog input module (2.4.1)

Covering HE693ADC406, HE693ADC405, HE693ADC415, HE693ADC410, HE693ADC420, the general requirements are as follows:

Calibrator: More than twice the accuracy of the module and powered by batteries.

Wire: Use high-quality wire that is the same as the wire used in the application and has the shortest length.

Environment: Avoid exposing the module to excessive EMI or RF, extreme temperature changes.

Installation and status: The module needs to be inserted into the PLC slot used in the application, and after being powered on and connected, it should be stable for at least 15 minutes. It should be installed vertically (in the panel installation position), and the PLC should be in "stop" mode; The unused channels during the calibration process of HE693ADC406 need to be short circuited and grounded.

2. Analog output module (2.4.2)

Regarding HE693DAC410 and HE693DAC420, it is required to be consistent with the analog input module (except for the channel short-circuit grounding of HE693ADC406).

3. Resistance Temperature Detector (RTD) module (2.4.3)

Including HE693RTD600, HE693RTD601, HE693RTD660, HE693RTD665, HE693RTD666, in addition to meeting the general requirements of the analog input module, there are additional requirements: unused channels during calibration must be short circuited and grounded; Modules with a suffix of -20 need to use the a=d switch (PT100D) in the calibration software.

4. Strain gauge module (2.4.4)

Including HE693STG883 and HE693STG884, it is required to be consistent with the RTD module (without using channel short-circuit grounding).

5. Thermocouple module (2.4.5)

Covering multiple models such as HE697THM160 and HE693THM166, in addition to meeting the general requirements for analog input modules, there are additional requirements: modules with a suffix of -21 need to use external ISOBLK for cold end compensation; During the calibration process, the last channel needs to be short circuited and grounded to optimize cold end compensation; Modules with suffix -02 need to use the "=k" switch in the executable file (refer to section 4.1).

Calibration process

（1） General Instructions (3.1)

The general calibration process is only a basic framework, with slight differences in the calibration process of each module, but the core logic is consistent. The simulation module needs to be calibrated according to the specific process described in the subsequent sections; Table 3.1 lists the simulation modules and their corresponding calibration files, with some corresponding relationships as follows:

Product model calibration software Product model calibration software

HE693ADC405 adc4x5.exe HE693THM166 thm166.exe

HE693ADC410、HE693ADC420 adciso.exe HE693THM665、HE693THM666、HE693THM668 thm668.exe

HE693ADC406 adc406.exe HE693THM884（REV. A,B,C） thm884_1.exe

（2） Software startup (3.2)

1. Startup steps

Select the corresponding executable file from the floppy disk list (for example, calibrate HE693THM884 and select Thm884. exe).

Enter the corresponding command at the DOS prompt to run the calibration program: when using the COM1 port by default, enter "Thm884" and press "ENTER"; When using the COM2 port, enter "Thm884=C2" and press "ENTER".

To view command line switches and their instructions, enter "Thm884=?" at the DOS prompt and press "ENTER".

2. Screen Example (3.2.1)

After the program starts, the top of the screen will display the program name and version. Taking the THM884 thermocouple module calibrator (V2.04) as an example, the screen will display channel values, types, scales, zero points, and other information, as well as module models, channel quantities, hardware alarms, versions, and other parameters. At the same time, it will prompt the functions of each function key (F1-F9, Esc) (such as F1 calibration of J-type thermocouples, Esc exit, etc.).

3. Windows version software installation and operation (3.2.2, 3.2.3)

Installation: Load the floppy disk containing the THM884cal.exe (Windows version) installation file, locate and select the setup. exe file, follow the prompts to select the application file storage directory, and after installation is complete, you can use it.

Run: Find THM884cal.exe in the directory specified during installation, double-click the file to open the application; This version operates similarly to the DOS version. If you have any questions about the functionality, press the F12 key to access the help file.

（3） Process Overview (3.3)

Disable non-volatile random access memory (NVRAM): If the "disable" option is not provided, it will be automatically disabled. This step closes the old calibration constant and uses the default value for new calibration. The module needs to be reset to use the default value.

Disable PLC configuration: Make the module use default values (the module defaults to PLC configuration mode when powered on).

Initialization module: Execute after disabling PLC configuration.

Perform calibration: If it is a thermocouple module, you need to first select the calibration type. The software will prompt you for each step in the calibration process, and you need to follow the prompts.

Update NVRAM: Update the new default values to NVRAM.

Activate NVRAM: Enable the module to use the stored calibration constants the next time it is powered on.

Re initialize the module: Let the module re read the calibration and filtering constants from the NVRAM.

（4） Module specific calibration process (3.4)

The calibration steps and corresponding function keys for each module are as follows (some module examples):

1. Analog input module (3.4.1)

4. Strain gauge module (3.4.4)

The calibration steps for HE693STG883 and HE693STG884 are the same as those for the analog input module.

5. Thermocouple module (3.4.5-3.4.7)

HE697THM160, HE697THM260: Follow the same steps as the RTD module.

HE693THM166: The steps are consistent with the analog input module.

HE693THM406 and other models: The steps are consistent with the RTD module.

HE693THM884 (K-type+channel offset calibration): Use THM884_K.bat batch file, consisting of 15 steps, including module installation, power on, NVRAM disable/activate, PLC configuration disable/enable, calibration execution, offset setting and transmission, NVRAM update, module initialization, etc. Some steps require the use of function keys such as F1, F4, F5, F6, F7, F8, and finally remove the module after power off.

HE693THM894 (K-type calibration): Use the THM894_K.bat batch file, following the same steps as HE693THM884 (K-type+channel offset calibration).

Switch settings

（1） Switch Description (4.1)

Many simulation modules can be temporarily configured and software switches can be used, such as observing the reaction of thermocouple modules using T-shaped thermocouple wires (rather than the commonly used J, E, R types); Please note that the=T,=K, and=C switches are volatile and will not cause permanent changes to the module, while commands such as=NVRAM (such as=S) will cause permanent changes. The switch format is "Thm884 [=C1] [=C2] [=T] [=K] [=Snnnn. n, nnnn. n, nnnn. n,...]", and the functions of each switch are as follows:

Switch Function Description

=C is used to select serial ports, for example=C1 (COM1),=C2 (COM2)

=T represents test mode, still transmitting command messages, but variables use internal values, receiving messages generated by simulation (software simulation mode), without the need to connect modules

=K sets the calibration type to K instead of the default J type

=Set calibration scale points for S, separated by commas (without spaces), in the order of K (or J) median, K high value, E median, E high value, R median, and R high value; When the value is 0, use the default value; If there are less than 6 entries, the remaining entries will use default values; The scale point must not be lower than 25 degrees Celsius (this low-temperature calibration point is crucial for optimizing cold end compensation)

（2） Example (4.2)

Command function

Thm884=C1 specifies COM1 as the serial port (default port)

Thm884=C2 specifies COM2 as the serial port (this command needs to be called to use COM2)

Thm884=T Enable test mode, transmit commands but only simulate messages, do not store values

Thm884=K sets the calibration type to K type (default J type), suitable for special applications and European calibration

Thm884 =S600.0,700
