Modbus User Map; Real Time Clock - GE G30 Instruction Manual

5.2 PRODUCT SETUP
• EXCH 1 DESTINATION: This setting specifies the destination IP address of the produced EGD exchange. This is usu-
ally unicast or broadcast.
• 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 G30 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.
