5.2 Setting Slave Address in the 32NT-DP
When setting the DP-slave address from the PLC follow the example program.
Example program
The following is an example of how to set the slave address to “10” of a 32NT-DP connected
as block No.0.

Initial pulse
The ID code for the 32NT-DP at
position “0” is read from BFM
#30 of that block and stored at D0 in
the main unit. This is compared
to check the block is a 32NT-DP, if
OK M1 is turned ON. These two
program steps are not strictly needed
to use the 32NT-DP. They are
however a useful check and are
recommended as good practice.
This command sets the slave
address to “10”.
