How does Scada system poll 4G Modbus IO module?
Usually, SCADA cannot directly poll 4g Modbus io module due to 4g network do not provide static public IP address for
simcard (except VPN), so CWT provide a Modbus TCP server tool to work with Scada in server,Modbus TCP serve
r only forward message between Scada and 4g Modbus IO module. So that realizes the connectivity of SCADA and CW
T 4g module.
Communication process:
1.CWT 4g module build connection with Modbus TCP server according to server IP address (in this case, static public IP
address or domain is necessary for server)
2.Scada system send Modbus TCP request command to Modbus TCP server tool
3.Modbus TCP server tool forward command to CWT 4g module
4.CWT 4g module responds
