Yokogawa Motor YS1700 Programmable Indicator Controller

Core positioning and overall advantages of the product

YS1700 is a programmable indicator controller that can be adapted to multiple scenarios through user programs. It belongs to the YS1000 series and its core advantages are reflected in high reliability, ease of use, and scalability. Specific features include:

Compact design: The standard version has a smaller volume and lighter weight (the base model weighs 1.6kg), with low installation space requirements. At the same time, it provides models with the same panel opening size and depth as the old controller, making it easy to replace and upgrade.

International Compliance: Compliant with CE certification, FM/CSA non flammable (optional) and other international safety standards, suitable for industrial scenarios in multiple regions around the world.

Dual CPU and Fault Safety: Dual CPU design for control and display, allowing for display and manual operation even in the event of a single CPU failure; A hard manual circuit independent of digital circuits (excluding suffix code -2xx options) that can manually adjust the output when both CPUs fail.

Maintenance free backup: using non-volatile memory to backup data, without the need for batteries or capacitors, reducing maintenance costs.

Wide voltage adaptation: Supports AC/DC dual power supply (such as 100V AC or 24V DC, 220V AC needs to be customized), DC power supply has no polarity limitation and strong resistance to voltage fluctuations.

Core functions and technical features

1. Display and operation functions

High visibility display: using a 120 × 320 pixel full dot matrix TFT color LCD, supporting backlight brightness adjustment and off, even in direct sunlight in the morning and evening, it is still clearly visible; Provide multiple display modes such as dashboard, trend chart, bar chart, alarm, event, etc., which can be quickly switched through panel buttons.

Flexible data display: The tag number can display up to 12 characters, PV (process value) and SV (set value) can display up to 7 digits (including decimal point and symbol), and MV (operation value) can display up to 6 digits; The trend chart supports three types of variables (such as PV1/SV1/MV1), with a time span of 1.5 minutes to 45 hours, and can hide/display a single curve.

Convenient manual operation: The panel is equipped with SV/MV increase and decrease buttons, supporting FAST mode (MV adjustment speed 4 seconds/full range, normal mode 40 seconds/full range); When there is a malfunction, it automatically switches to FAIL display, and the hard manual wheel can adjust the output urgently.

2. Control mode and computing power

Dual control mode:

Programmable mode: Requires YSS1000 configuration software, supports basic control (BSC1/BSC2), cascade control (CSC), selector control (SSC) modules, and can freely combine control and calculation modules.

Function selection mode: No programming required, select commonly used functions (single loop, cascade, selector control) directly, and I/O functions are allocated through parameters.

Rich control types: Supports four control types: PID, PD, sample and hold PI, and batch PID. PID parameters (proportional range 0.1-999.9%, integration time 1-9999 seconds, differentiation time 0-9999 seconds) can be flexibly set, and additional functions such as self-tuning (STC), nonlinear PID, and output limitation can be added.

High precision calculation: using IEEE754 format 4-byte floating-point operation, supporting over 100 calculation modules such as exponential, logarithmic, temperature/pressure compensation, etc., to ensure data processing accuracy.

3. Programming and debugging skills

Dual programming mode:

Text programming: Program capacity of 1000 steps (main program+subroutines, subroutines can be reused), supporting logical operations, conditional judgments, jumps, and other instructions.

Function block programming: Based on GUI interface, with a program capacity of 400 modules, supporting online monitoring and testing operation, reducing programming barriers.

Online debugging: Through YSS1000 software, program testing, I/O signal simulation (up to 50 steps of simulation program), and functional block status monitoring can be achieved for easy troubleshooting and parameter optimization.

Data storage: Provides 30 P-parameter variables, 100 K-parameter constants, and 60 temporary data registers to meet the data storage needs of complex programs.
