Add more drives (optional)
In the CODESYS "POUs" tab, right‐click the program for your earlier drive and choose "Copy Object", give the new

Network 0001 to Network 0002 and rename the block in Network 0002 to according to your new program.
Double‐click and open the new program. Change "SLAVE" number of the "ACS_COM_MOD_RTU" block according

Continue to add as many drives as you need. If you want to create visualization pages/objects for the additional
drives, make sure that you connect the Placeholders to the function block instances for the correct program (PRG),
