The C500-TS502 has internal RAM for storage of operating parameters dur-
ing execution. Internal EEPROM memory provides non-volatile storage for
these parameters without the need for batteries. Both memory areas have a
module memory map which defines the operating parameters for the module.
This module memory map is uploaded from EEPROM on power up and used
by the module during operation. The EEPROM default parameters may be
customized and changed by the user to meet the application requirements.
The table on the next page is an outline of the complete module memory
map. The module memory map has read/write and read only areas. These
are marked in the module memory map. A detailed functional description of
each location and default values are also provided.
Both bits and flags are arranged in the following format and correspond to
the input points indicated below.
Default values and valid data ranges for all module memory map words are
in Appendix E.
Data in the module memory map can be formatted in either signed BCD or
2’s Complement Binary. All values for a specific input point must be in the
same format. Some values are entered in unsigned BCD. Reference Appen-
dix E for valid data ranges for all module memory map locations.
There are a number of memory map error flags in the module which can be
used to verify status and operation. These flags include:

Signed BCD
2’s Complement Binary

Indicates a memory location in the PLC data memory or in
the module memory map. A word can contain a single
piece of data or it can contain bits or flags for each of 8
input points (see format below).
Set by the user to enable a particular function.
0=OFF/DISABLE, 1=ON/ENABLE
Set by the module to indicate status of a module function.
