Mark V - IO_CFG.LST Change Detection for SOE

in IO_CFG.LST u can check under TCDA card definition (just search for TCDA) u can see that the Chg Det is set to 1 (which is ENABLED).

Having this turned on for that particular card / contact input will enable Change Detection for SOE purposes.

On the other hand, u can check CONFIG.DAT to see whether SOE will be printed or not. Having SOE enabled does not necessarily required it to be printed (at least this is the case at PPSB Power Plant).
