Modbus User Map - GE C30 Instruction Manual

5.2 PRODUCT SETUP
• EXCH 1 DATA RATE: This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms,
the exchange data will be updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data will be
updated and sent once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a
setting range of 500 to 1000 ms.
• EXCH 1 DATA ITEM 1 to 20/50: These settings specify the data items that are part of this EGD exchange. Almost any
data from the C30 memory map can be configured to be included in an EGD exchange. The settings are the starting
Modbus register address for the data item in decimal format. Refer to Appendix B for the complete Modbus memory
map. Note that the Modbus memory map displays shows addresses in hexadecimal format; as such, it will be neces-
sary to convert these values to decimal format before entering them as values for these setpoints.
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (for example, 32 bit integers and floating point values),
only the first Modbus address is required. The EGD exchange configured with these settings contains the data items
up to the first setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid
Modbus addresses and the fourth is 0, the produced EGD exchange will contain three data items.

These settings appear only if the C30 is ordered with an Ethernet switch module (type 2S or 2T).
The IP address and Modbus TCP port number for the Ethernet switch module are specified in this menu. These settings
are used in advanced network configurations. Please consult the network administrator before making changes to these
settings. The client software (EnerVista UR Setup, for example) is the preferred interface to configure these settings.
