PACSystems CPU models have the following features in common:
■ Programming in Ladder Diagram, Function Block Diagram, Structured Text and C.
■ Floating point (real) data functions.
■ Configurable data and program memory.
■ CPE305 and CPE310 have battery-less retention of user memory non-volatile flash. All other
models have battery-backed RAM for user data (program, configuration, register data, and
symbolic variable) storage and clocks.
■ CPE305 and CPE310 models have battery backup for real time clock (elapsed time clock).
■ Non-volatile built-in flash memory for user data (program, configuration, register data, and
symbolic variable) storage. Use of this flash memory is optional.
■ Configurable Run/Stop mode switch.
■ Embedded RS-232 and RS-485 communications. (CPE305 has only RS-232 communications).
■ Up to 512 program blocks. Maximum size for a block is 128KB.
■ Auto Located Symbolic Variables, which allows you to create a variable without specifying a
reference address.
■ Bulk memory area accessed via reference table %W. The upper limit of this memory area can be
configured to the maximum available user RAM.
■ Larger reference table sizes, compared to Series 90* CPUs: 32Kbits for discrete %I and %Q and
up to 32K words each for analog %AI and %AQ.
■ Online Editing mode that allows you to easily test modifications to a running program. (For details
on using this feature, refer to the programming software online help and Proficy Logic Developer
Getting Started, GFK-1918.)
■ Bit in word referencing that allows you to specify individual bits in a WORD reference in retentive
memory as inputs and outputs of Boolean expressions, function blocks, and calls that accept bit
parameters.
■ In-system upgradeable firmware.
1.3.1 Firmware Storage in Flash Memory
The CPU uses non-volatile flash memory for storing the operating system firmware. This allows
firmware to be updated without disassembling the module or replacing EPROMs. The operating
system firmware is updated by connecting to the CPU with a PC compatible computer and running
the software included with the firmware upgrade kit.
1.3.2 Operation, Protection, and Module Status
Operation of the CPU can be controlled by the three-position Run/Stop switch or remotely by an
attached programmer and programming software. Program and configuration data can be locked
through software passwords. The status of the CPU is indicated by the CPU LEDs on the front of the
module. For details, see “Indicators” for each PACSystems family.
Note: The RESET pushbutton is provided to support future features and has no effect on CPU
operation in the current version.
