  • Page 92: Communication Protocol

    The master controls communication between master and slave. A typical message consists of a request (query message) sent from the master followed by an answer (response message) from the slave (SRZ). When master begins data transmission, a set of data is sent to the slave in a fixed sequence. When it is received, the slave decodes it, takes the necessary action, and returns data to the master.

  • Page 333: Peak Current Suppression Function

    11. APPENDIX 11.5 Peak Current Suppression Function When the output type is time proportional output, the Peak current suppression function changes the start timing of the proportional cycle so that the outputs of the channels do not turn ON simultaneously. The Peak current suppression function operates within one Z-TIO module.
  • Page 334 11. APPENDIX The use of peak current suppression function in the load used in the three phase power supply system may not suppress the peak current. This is because the peak current suppression function works on condition that the target (object) channels are time-proportionally controlled on the voltage with the same frequency.
