ADDRESSES

The L30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to

which the L30 can connect.

A maximum of two simultaneous connections are supported at any given time.

p) IEC 60870-5-103 PROTOCOL

PATH: SETTINGS  PRODUCT SETUP  COMMUNICATIONS  IEC 60870-5-103

The L30 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: This setting uniquely defines this L30 on the serial line. Select an ID between 0 and

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.

IEC103 SYNC TIMEOUT: This setting defines the time that the L30 waits for a synchronization message. The L30 synchro-

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 L30 sets the invalid bit in the time stamp of a time-tagged message.
