Configuration of the M2C Programmable Contacts

General Description

The M2C has two programmable contacts, 1 and 2, that may be used to signal pick-up value overruns or status changes.

The M2C programmable contacts can be configured remotely via the communication interface.

M2C Programmable Contact Registers

The settings of the M2C programmable contacts are in the contact registers:

Contact Number	Contact Addresses	Contact Registers
1	0x2648–0x264E	9801–9807
2	0x264F–0x2655	9808–9814

M2C Programmable Contact 1 Description

The order and the description of the M2C programmable contact 2 is the same as that of contact 1:

Address	Register	RW	X	Unit	Type	Range	Description
0x2648	9801	RW	–	–	INT16U	0–4	Output mode
							0 = normal (non-latching) mode (factory setting) Contact closed each time for as long as the assigned alarm remains active.
							3 = forced to 1 The contact remains closed and is not controlled by the alarm status.
							4 = forced to 0 The contact remains open and is not controlled by the alarm status
0x2649–0x264D	9802–9806	–	–	–	–	–	Reserved
0x264E	9807	RW	–	–	INT16U	1000–1031	Owner alarm number for the contact 1. Factory setting = 0x8000 (no owner)

Event Assignment to M2C Programmable Contacts

The M2C programmable contacts can be associated to a protection parameter event.

Depending on the protection parameter, a specific register can contain the programmable contact number which opens or closes at the end of the protection time delay (register 8763 as example).
