2-6 Installation and Wiring
Set the Station Address on the 1790P-T4R0 PROFIBUS DP Base Block
To set the station address, adjust the switches on the front of the base
block. The two switches are most significant digit (MSD) and least
significant digit (LSD). The switches can be set between 00 and 99.
The rotary switches are read at base block power up only .
Mounting Mount the Base Block
You can mount the base block to a panel or DIN rail. We recommend that
you ground the panel or DIN rail before mounting the block.
Panel Mounting
1. Place the block against the panel where you want to mount it.
2. Gently pull and position the expansion cover to the left.
3. Place a center punch, nail or similar device through the mounting
holes in the block and make two marks on the panel (lower left and
upper right corners of the module).
4. Remove the block and drill two holes in the panel to accommodate
each of the mounting screws.
Example: Node
Address is set at 26

IMPORTANT
The RTD and thermocouple base modules
do not support any expansion blocks.
