AutomationDirect GS4 Drives Ethernet Setup

 Topic: CM060

The GS4 Drive Modbus TCP/IP Protocol allows C-more to easily and directly access the drive parameters to view or adjust over an Ethernet Connection. The GS4-CM-MODTCP module for the GS4 driver is required.

Field Description
IP Address The GS4-CM-MODTCP module IP address.
PLC Port Specifies the destination TCP port number that C-more sends to the GS4. 502 is the standard default. Sometimes this number needs adjustment for firewall/router purposes.
PLC Slave Number Corresponds with the “Unit ID” number in the protocol header. You can set this number to any value, as the GS4 will echo the value. You can use this field in the future for gateway/routing purposes.
Register Write Function Code This field is preconfigured to work with the GS4 drive.
Coil Write Function Code This field is preconfigured to work with the GS4 drive.
Retries The C-more panel sends a request to the specified device. If the device does not reply within the specified time, the C-more panel sends the request again. Once the retry count (specified in this field) limit is reached, the C-more panel displays a PLC Timeout error on the screen.
Timeout Time The amount of time (in 100ms units) that the panel waits on a reply after sending a request. After the timer expires, it retries.
Poll Time The amount of time (in milliseconds) that the panel waits in between each request.
