Modbus User Map; Real Time Clock - GE G60 Instruction Manual

5 SETTINGS
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 (e.g. 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.

MESSAGE
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 line (this value must be converted from hex to decimal format). The corresponding value is dis-
ADDRESS
played in the line. A value of "0" in subsequent register
VALUE
lines incremented by "1". An address value of "0" in the initial register means "none" and values of "0" will be dis-

played for all registers. Different
These settings can also be used with the DNP protocol. See the DNP Analog Input Points section in Appen-
dix E for details.

MESSAGE
The date and time for the relay clock can be synchronized to other relays using an IRIG-B signal. It has the same accuracy
as an electronic watch, approximately ±1 minute per month. An IRIG-B signal may be connected to the relay to synchronize
the clock to a known time base and to other relays. If an IRIG-B signal is used, only the current year needs to be entered.
