30.1 Controlling External I/O

To control external I/O in a logic program, map addresses (variables) to I/O terminals. You need to identify which addresses (variables) send outputs, and which addresses (variables) read inputs. Setup procedures vary depending on whether you use the built-in I/O terminals for the display unit, or I/O terminals in an external unit.

When using the built-in I/O terminal

• AGP-XXXXX-D81

• LT Series

Setting Procedure

1. Set up I/O Driver. Once the model is selected, I/O Driver is automatically set up.

2. Map addresses (variables) to I/O terminals.

When using an external unit

• AGP-XXXXX-FN1M + FLEX NETWORK unit

• AGP-XXXXX-CA1M + HTB unit + EX module

• AGP-XXXXX-CA1M + Slave unit provided by other companies

• LT Series + EX module

• LT Series + HTB unit + EX module

• LT Series + Slave unit provided by other companies

Setting Procedure

1. Set up I/O Driver. Once the model is selected, I/O Driver is automatically set up.

2. Specify the model of the external unit.

3. Map addresses (variables) to I/O terminals.
