With a counter module (NP1F-HC2), I use ２ counter FBs to control 2 channels. At system start-up, I set simultaneous preset operations for the 2 channels but preset is performed only on 1 channel. Why?

Answer

Check to make sure that_ (1) The channel specification (CH_SEL) is correct. (2) The FB instance names are not duplicated. (3) The preset command is given after initialization completion (INI_END) has been turned on.
