Examples Using CompoWay/F Commands Section 6-3
Operation 2 (Reading
PV)
• Reads the PV for E5ZN (Temperature Controller) unit number 0, ch1.
FINS-mini command: Reads the PV of ch1. MRC = 01 hex, SRC = 01 hex
(Read from Variable Area), variable type 00 hex, and read start address =
0000 hex.
• The data is read using the EXPLICIT MESSAGE SEND command (2801).
• The command data is written in DM words starting from D01020 in the
CPU Unit's memory, and the response data is stored in DM words starting
from D01220.
• If the command does not end normally, the end code is stored in D01126
and the send command is re-executed.
