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.

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.
