Modbus Operating Modes
MASTER Processes and displays data read from Modbus RTU slave devices. Up to 16
process variables (PVs) from up to 16 slave devices. Each PV programmed
individually.
SLAVE Processes data sent to it from a Modbus RTU master device.
Note: Refer to Modbus Register Tables at www.predig.com for details.
SNOOPER Listens to the Modbus traffic and picks up a specific register or registers being
polled by a Master device from a specific slave device and processes the data
being read. Up to 16 process variables (PVs) from up to 16 devices. If multiple
registers are polled by the master with one command, only the first returned
value will be read.
MASTER POLL TIME 0.1 to 99.9 sec. Time between read-commands.
MASTER TIMEOUT 0.1 to 99.9 seconds. Time elapsed after a poll request is made before the
scanner considers that request to have failed.
NUMBER OF RETRIES 1-99. The number of retries the scanner will make when requesting data before
reporting an error condition on the PV.
SNOOPER
RESPONSE TIME 0.1 to 99.9 seconds. Time since the last PV update the before being
considered an error.
SLAVE TIMEOUT 0.0 to 99.9 seconds. Time elapsed after the last data received from a master
before the scanner considers the data to be out of date. Programming 0
disables the timeout, and PV data will be displayed indefinitely despite not
being updated regularly.
