F-26 1788-CN2FF Installation Example

Changing a Tag Name

You can change the names of the Fieldbus Devices, and most of the
function blocks so they have meaning in your application.

1. Right click on a Function Block.

2. Select Set Tag.

3. Type any name that fits your application.

Short names are easier to read in Device Info which you’ll use
later.

4. Check the Device addresses.

The devices on your fieldbus should automatically be assigned a
network address in the range of 16-36. This MAX address is
based on the setting of the First_Unpolled_Node_ID.

Check the address that was assigned to each device. Devices
which have LM, Link Master, capability should have addresses of
23 or higher.

5. Right click on LM devices.

6. Click Set Address.

If the address is less than 23, pick a new available address. The
CN2FF should be at FF address 16. If not, change the address to
16.

7. Select Set Tag.

IMPORTANT

Do not attempt to change the names of the Function
Blocks in the 1788-CN2FF. If you change these
names the 1788-CN2FF will not work properly.
