Iec 60870-5-103 Protocol - GE T60 Instruction Manual

5 SETTINGS
• 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 T60 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.

The T60 is provided with optional IEC 60870-5-103 communications capability. This feature is specified as
a software option at the time of ordering. See the Order Codes section in chapter 2 for details.
The IEC 60870-5-103 protocol is enabled when the
ting is set to IEC 60870-5-103.
IEC103 COMMON ADDRESS OF ASDU
254. This ID does not need to be in sequential order for all stations that communicate with a controller, but it is recom-
mended. Note that RS485 only allows a maximum of 32 slave stations on a communication line, so the entire range of 254
addresses is never exhausted.
: This setting defines the time that the T60 waits for a synchronization message. The T60 synchro-
IEC103 SYNC TIMEOUT
nizes its clock using all available sources, with the source synching more frequently overwriting the time of the other
sources. Since the synchronization message received from the IEC 60870-5-103 master is less frequent than IRIG-B, PTP,
or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs and
none of IRIG-B, PTP, or SNTP is active, the T60 sets the invalid bit in the time stamp of a time-tagged message.
The settings for the remaining menus are outlined as follows.
