• 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 G60 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.

MODBUS USER MAP
The Modbus user map provides read-only access for up to 256 registers. To obtain a memory map value, enter the desired
address in the
ADDRESS
line (converted from hex to decimal format). The corresponding value displays in the
VALUE
line. A
value of “0” in subsequent register
ADDRESS
lines automatically returns values for the previous
ADDRESS
lines incremented
by “1”. An address value of “0” in the initial register means “none” and values of “0” display for all registers. Different
ADDRESS
values can be entered as required in any of the register positions.
