RELAY REGISTER OFFSET

The Relay Register Offset is located within the A24/32 address space of the module. When you send data to the register, the relay register offset is added to the A24/A32 base address and module base address:

Relay Register Address = A24/A32 Base Address + Module Base Address + Register Offset

or

Relay Register Address = Module Relay Address + Register Offset

WRITING TO THE RELAYS

Each bit of a 16-bit register represents the state of the relay (1 = closed, 0 = open). To change the state of any relay, it is only necessary to write a 16-bit integer to the specified register with the new configuration:

Relay Register Address, data

	For example:
	• writing a data value of "0" to the register at offset "0" would open the first sixteen relays
	• writing a data value of 65535 to the same register would close the first 16 relays
	• writing a data value of 65534 to the same register would close all relays except K1, which
	would be open

NOTE	Energize only one coil in a group of six at one time.
