Product Line
Satchwell Sigma
Environment
- IC3 Modbus
- TCP502
Cause
Configuration not documented in release note
Resolution
More than one device can be mapped via the same IP Address. For example the gateway.txt file can be:
1,1,3,1,1,0x0001,0,0,1 ;Modsim1 40001 2,1,3,2,1,0x0001,0,0,1 ;Modsim1 40002 3,2,3,1,1,0x0001,0,0,1 ;Modsim2 40001 4,2,3,2,1,0x0001,0,0,1 ;Modsim2 40002 5,3,3,1,1,0x0001,0,0,1 ;Modsim3 40001 6,3,3,2,1,0x0001,0,0,1 ;Modsim3 40002 7,4,3,1,1,0x0001,0,0,1 ;Modsim4 40001 8,4,3,2,1,0x0001,0,0,1 ;Modsim4 40002 OUTPUT ; IP_ADDRESS_TABLE 1,10.158.72.254 2,10.158.72.254 3,10.158.72.254 4,10.158.72.254 ;Do not write below this line
Note: The IC3 Modbus can only be mapped to a single IP Gateway or PC application, and it is not possible to map to two applications on the same PC.
