Registration Numbers will always remain the same. I/O modules in a system are identified in general by their model number (MAQ20-VDN, MAQ20-JTC, etc.) and uniquely by their Serial Number printed on the side label (i.e. 1234567-89). When I/O modules are installed in the system, only a general identifier is visible on the front of the module (V, I, TCPL, etc.). -

Observe that the green Power LED is on and that there is communications activity on the TX and RX LEDs. Allow 1 second for registration. This module now has the same Registration Number as the one removed. - Page 13 MA1047 MAQ20-JTC/-KTC/-TTC/-RSTC Hardware User Manual STANDARD EXPANSION PROCESS 1.) Turn system power on and observe communications activity on the I/O modules. 2.) Add a single MAQ®20 I/O module in any local or remote backbone position. Observe that the green Power LED is on, and communications activity is seen on the TX and RX LEDs. Allow 1 second for registration.
