4.15 Loop Address Utility
In order for the MCTB to properly communicate with each of the loop control boards, they must be configured
for the proper communications address. The factory default communication settings of the loop control boards
are set for a communications address of one, which correspond to the proper settings for loop 1. For a single
loop MCTB control system, no further settings are required. Simply connect the communications wiring
between the control board and the MCTB interface, and the system is ready to go.
For a dual or three loop MCTB control system, the other loop control board(s) must be set for addresses two
and three which corresponds with loop 2 and 3 respectively. If a display module is not available to connect to
the loop control board in order to set its address, the Loop Address Utility can be used. It is accessed from the
Setup menu.
In order to use the utility, only one loop control board can be connected to the MCTB at a time. Since the
default address of all loop controls are 1, if more than one was connected, they would both respond to the same
command which would cause them both to be set to a different address. If more than one loop control board
or limit is connected, disconnect the communications wiring from the limit and loop control board(s) that you
DO NOT want to set the address on. An alternative is to remove power from the limit or loop control board(s)
rather than disconnecting the communications wiring.
With only one loop control board powered on or connected to the MCTB via the communications link, press the
Loop Number field and enter the address to assign to the attached loop control. Once entered, press the
“Assign Address” button and the utility will begin scanning for the loop control board and set its address to the
one entered once found. If the utility fails to set the address, check the wiring to insure it is properly connected.
If the loop control board has been previously used for another application, it may be possible that the address
or other communications settings have been changed, which prevent the utility from working. In this case, a
display module must be connected to the loop control board to set the proper communications settings:
Address: 1, 2 or 3 (for loop 1, 2 or 3)
Baud rate: 9600
Parity:
Even
IMPORTANT: The loop input number corresponds to the communications address that must be set in the
loop control board for the MCTB to access it properly. If the communications address is not
set properly in the loop control, the MCTB will not be able to communicate with it or may
communicate with the wrong loop control and assign the incorrect set points and control
parameters to it.
