When VarBit1 in FB0 is ON, HCPoint1 (HC0) is ON. Network: When StartBit[1] is ON, the address of CVar1 is transmitted to HCPoint1 in FB0.
When VarBit1 in FB0 is ON, HCPoint1 (CVar1) is ON. 4.9 File Register DVP-ES3 Series PLC provides File registers (FR) for storing larger numbers of parameters. You can edit, upload, and download the parameters in the file registers with ISPSoft. The values in file registers can be read while the PLC is running.
