Item Address Details using DASMBTCP
All RMC data registers are of Modbus memory type "4".
In the Item box in the Tagname dictionary, adding " F" to the end of the Modbus address
indicates it is a floating-point number. Adding " L" to the end of the Modbus address
indicates it is a 32-bit integer. Adding ":" and then the number, such as "404097:1"
treats it as a discrete, with number after the colon indicating the bit number. Wonderware
counts bits starting at 1.
Calculating RMC Register Addresses
Use the Register Maps to find the Modbus/TCP addresses of the desired registers in the
RMC75E. You can also use the Modbus Addressing topic to easily convert the two-level
addressing to Modbus addresses.
