B.6.5 VIRTUAL INPUTS WRITING
For forcing Virtual Inputs, a message with 4 indivisible records must be written at address, so that each bit corresponds to a
Virtual Input. Values will not be correct if the first 4 records are not written in the same message. The first 32 are LATCHED
(internally stored with RAM with battery), and the last 32 are SELF-RST (activated to 1 and deactivated in the next pass by
the PLC).
For reading the status of Virtual Inputs, it is necessary to start with address 0x0083(bit 0x004) up to 0x0087 (bit 0x0200).
