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.
■ Battery-backed RAM for user data (program, configuration, register data, and
symbolic variable) storage
■ Non-volatile built-in flash memory for user data (program, configuration, register data,
and symbolic variable) storage. Use of this flash memory is optional.
■ Battery backup for program, data, and time of day clock.
■ Configurable Run/Stop mode switch.
■ Embedded RS-232 and RS-485 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 – PLC 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.
