Inserting Coding Keys
For 753 Series I/O modules, the connection between the I/O module and the pluggable connector can be coded. For the coding, proceed as follows:
- Insert the pin into the socket.
- Position the assembled coding keys in the I/O module.
- Due to its design, each coding pin allows four different coding options (i.e.; 16 different options using two coding keys).
- Put the pluggable connector on the I/O module.
- After removing the pluggable connector, the sockets remain in the I/O module.
