7. PLC2Way 3-51
Serial Communications
• $s762
Periodical reading that is set in the [Temp. CTRL/PLC2Way Table Setting] dialog can be
suspended.
- [0]: Periodical reading is performed.
- [Other than “0”]: Periodical reading is suspended.
If periodical reading of the temperature control network/PLC2Way table is performed
while the PLC2 memory is being accessed using a macro command, the macro
execution will be delayed (Fig. a). To avoid this, periodical reading can be suspended
using memory address $s762 (Fig. b).
• $s763
Forced execution of macro commands [TEMP_READ] and [TEMP_WRITE] using the
temperature control network/PLC2Way table
- [0]: When any station that has failed is included in the specified table,
the macro command is not executed.
- [Other than “0”]: The macro command is forcibly executed to the stations that are
working properly.
