App1-22 Appendix 1 PLC2Way
• $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.
