Chapter 5: Word and Bit References
19
Word Referencing Method
The general word referencing method is:
[plcname,word#format]
The "plcname" is the name of the designated PLC as listed in the PLC Name and Port Table. The
"word" is the reference number (address) of the word or register to be read or written. The "#format"
is a code which specifies the format of the data being read or written. The "plcname" and "#format"
are optional if you are using the default PLC and do not wish to change the data format, respectively.
The general bit referencing method is:
[plcname,bit]
The "plcname" is the designated PLC as listed in the PLC Name and Port Table. The "bit" is the
reference number (address) of the bit, coil, or input to be written or read.
See the "Word and Bit References" topic in the Configuration Software Online Help for a more
detailed explanation of word and bit references, including format descriptions.
The Reliance AutoMate PLCs use octal register addresses. The PanelMate unit format default is S16.
The following is the format for a register reference:
[rr]
rr
PLC reference number of the register.
The following is the format for a register bit reference:
[rr.bb]
rr
PLC reference number of the register.
bb
PLC reference number of the bit.
Note:
A period (.) must be between the register and bit reference numbers.
The Memory Ranges table on page 4 of Chapter 1, shows the maximum amount of memory available
for the specific Reliance model. Your PLC may or may not have the maximum amount of memory.
The driver supports a maximum of 60 contiguous words per read. The Operator Station generates
another read when more than 15 unused PLC words are encountered.
