Setting the Unit Number
Note
8. Ground the Power Supply Unit to a resistance of 100
The GP-IB connector’s shell is internally connected to the Power Supply
Unit’s ground terminal (GR) through the CPU Rack or Expansion Rack. Con-
sequently, the GP-IB cable’s shield is grounded by grounding the Power Sup-
ply Unit’s ground terminal (GR).
If the connected device is equipped with a ground terminal, we recommend
grounding that terminal.
Set each Unit’s unit number with the rotary switches on the front of the Unit.
The unit numbers are used to identify the Special I/O Units in the PLC. The
GP-IB Interface Unit’s unit number may be set to any decimal number
between 0 and 95. (The factory setting is 0.)
Use a small slotted screwdriver to turn the rotary switches and do not damage
the switch while changing the setting.
1. Always turn OFF the PLC before changing the unit number setting.
2. The unit number is set to “0” at the factory.
Rack or Expansion Rack where the GP-IB Interface Unit is mounted.
Create new I/O tables in the PLC after setting the unit number for the first
time or changing the setting.
Do not set the same unit number on more than one Special I/O Unit in a
PLC. If the same number is set on two or more Special I/O Units, a Special
I/O Unit setting error will occur and the GP-IB Interface Unit will not be rec-
ognized from the PLC.
The unit number setting determines which DM area words are allocated to
the Unit in the PLC.
