Control Information for the 1260-37B
The following information describes the control-register-to-relay-channel mapping for a 1260-37B
Relay Module. This information may be used to control a 1260-37B 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. 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 between logical channels used to operate the relay module in
message-based mode and the bits within the Control Registers which may be used to operate the
channel in register-based mode.
Each Control Register is located 2 addresses from the previous Control Register. 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.
