6. Special Installation Instructions
6.1 Unit Address Setting
An IIB must be programmed with two unit addresses:
1. the address of the Comparator I/O Module it will operate with
2. the IIB’s own address
You only need to perform this programming once, at installation time. These
addresses are stored in non-volatile memory so the only reason that you would
have to repeat this step is if you changed the unit address of the Comparator I/O
Module or if you replaced the IIB module.
Before programming the address information into the IIB, determine the unit
addresses of all the MCN modules in the system, following the guidelines in the
Address Planning planning section of the Monitoring and Control Network
System Manual (reference 1).
Valid ranges for the Group and Module switches are:
•
Group number = 00 through FE
•
Module number = 0 through F
The steps for programming the unit address of the Comparator I/O Module are:
Step Action
1 Determine the unit addresses of all the MCN modules in the system.
2 Apply power to the IIB.
3 Place OPTION switch 4 in the UP position.
4 Set the Group and Module switches to the unit address of the
Comparator I/O Module (from step 1) that this IIB will operate with.
5 Press the RESET button on the IIB.
6 The ERR LED will turn on and remain on.
7 Place OPTION switch 4 in the DOWN position.
8 Set the Group and Module switches to the unit address of this IIB
(its own address from step 1).
9 Press the RESET button on the IIB.
10 The ERR LED will turn on momentarily and then turn off.
After you complete these steps, connect the IIB to the Comparator I/O Module.
Apply power to the Comparator I/O Module and within approximately three
seconds, the ACT LED of the IIB should turn on and the ACT LED of the
Comparator I/O Module should turn on or blink. If the ACT LEDs turn on, the
IIB has been correctly programmed with the unit address of the Comparator I/O
Module. If the ACT LEDs remain off, verify your unit switch settings and repeat
