To assist in the custom configuration of the module, a Configuration Work-
sheet has been provided in Appendix D. Values for all intelligent functions
can be entered in the worksheet. These values can then be easily transferred
to data memory for use by the module.
The C500-TS502 Analog Input Module communicates with the program-
mable controller using the 2-Word Mode when the 2/4 word mode jumper is
set in the 2-word position. The intelligent I/O read/write instructions are used
to transfer data between the PLC and the module memory map. Details of
these instructions can be found in the Operation Manuals for the controllers.
For jumper settings, refer to Section 2 in this manual.
This section describes the bit assignments and the functions for the two I/O
words that the module occupies in the programmable controller I/O table.
The module communicates with the PLC using two word mode addressing.
The I/O read and I/O write ladder instructions are used to read/write data be-
tween the module and the PLC. The module requires two words in the I/O
table, one output word from the PLC to the module, and one input word from
the module to the PLC. The functions of these words are described in the
table below.
Function
Setting this bit to ‘1’ triggers the module to write
the current RAM configuration to EEPROM
memory in the module. On power up, the new
parameters will be the default start up
parameters.
Setting this bit to ‘1’ enables the serial port on
the module to write to the module memory
map. A ‘0’ disables writing from the port.
Setting this bit to ‘1’ resets bit 5 of word n+1,
the Low/High Alarm Flag and the low/high
alarm flags in memory words 00 and 09.
Setting this bit to ‘1’ resets bit 6 of word n+1,
the Under/Over Range Flag; resets the under
range and over range flags in memory word 10;
and resets the open RTD flags in memory word
83.
Setting these bit to ‘1’ resets the peak hold
register in the module memory map for the
input points specified.
