Appendix 1 PLC2Way
Processing Cycle
The processing cycle on the V7 series with the PLC2Way function is explained.
1.
When the temperature control network/PLC2Way table is not used:
Fig. 1
2.
When the temperature control network/PLC2Way table is used:
Fig. 2
When the temperature control network/PLC2Way table is not used (Fig. 1), PLC data is not read while
the data is read from the PLC connected at the MJ port.
When the temperature control network/PLC2Way table is used (Fig. 2), PLC data is read while the
data is read from the PLC connected at the MJ port.
Consequently, it is possible to communicate with the PLC connected at the MJ port without reducing
the processing capacity between the V7
↔
the PLC.
When the temperature control network/PLC2Way table is used:
If periodical reading of the PLC data is performed while the PLC connected at the MJ port is
accessed using a macro command, the macro execution may be delayed. It is possible to
temporarily stop periodical reading from the PLC connected at the MJ port using the system
memory address ($s762). For more information, refer to page App1-22.
