Control Information for the 1260-50A and –50C
The following information describes the control-register-to-relay-channel mapping for a 1260-50A and 1260-
50C Relay Modules. This information may be used to control a 1260-50A (50C) when using a 1260-01T in the
register-based mode of operation.
Each relay on this module is controlled by setting or clearing a single bit within a Control Register. Control
Registers on the module operate 8 channels simultaneously. There are eight control bits per Control Register.
Setting the bit to a 1 closes the relay; setting the bit to a 0 opens the relay.
The table below shows the mapping from logical channels to control bits. The logical channels are used when
operating the relay module in message-based mode. The control bits within the Control Registers are used to
operate the module in register-based mode.
Each Control Register is located 2 addresses from the previous Control Register. That is, each Control
Register is located at an odd address. This is shown in Table 2-2 of the 1260-01T manual. Control Register 0
is located at the “Base A24 Address” for the module. Consult the “Register-Based Operation” Section of
Chapter 2 of the 1260-01T manual for a description of calculating control register addresses.
