86 PCS100 AVC-20 User Manual
The Modbus TCP server responds to reads from the cached addresses in typically less than 3 milliseconds.
However, the latency in a parameter changing value (the time it takes for the cached values to be refreshed) is
typically around 3 seconds.
10.3.3 Modbus TCP User Parameters
The following table lists the user parameters available from the PCS100 AVC-20.
The address listed is the offset (raw) address. For 4xxxx address add 40001 to the offset address. Each address
refers to a 16-bit register.
