CONCEPT time synchornisation

Is it possible to set the time by directly writing the registers from another device ?

My PLC is following the time of my PC is it possible to directly write registers (with PI system) to synchronize a clock ?

How may I do this (I am using concept software from Modicon)?

If anybody needs to know for futur use, there is a function SET_TOD in CONCEPT(set time of day) that can do this.

Best regards
