I/O Interface Current
Consumption
Make sure that the power supply from the Communications Unit to the I/O
Units is less than the total rated output current (400 mA). The I/O interface
current consumption for each I/O Unit is shown in the following table.
Calculation Example
When five GT1-ID32ML Input Units and three GT1-OD16 Output Units are
used, the total current consumption is calculated as follows:
(GT1-ID32ML current consumption) x 5 Units
+ (GT1-OD16 current consumption) x 3 Units
= 55 mA x 5 + 35 mA x 3 = 380 mA
≤
400 mA
I/O Unit Interface
Addresses
The addresses of the I/O Units on the I/O Unit interface are automatically set
when the Communications Unit is started. The addresses are from 0 to 7 in
ascending order from the I/O Units closest to the Communications Unit.
Checking the I/O Unit
Interface Status
The following two methods are used to check the I/O Unit interface status:
• Checking the Communications Unit and I/O Unit indicators
• Checking the status of the Communications Unit
