Siemens Industry, Inc. TALON TX-I/O Modules and Island Bus Technical Reference

If too many of these outputs are configured, the voltage may drop too much so that all
modules switch off. When the voltage recovers, the modules switch on again, and so

5 cycles (shortcut between CD and CS, the COM LED will light brightly).
