be installed on the communication cable of the last instrument, as indicated in Figure 32.
5.3.2 Sent data
Every channel sends the following information:
• Channel status (1 byte) Information about the status of relays, alarm, etc.
• Units (1 byte).
• Measured value (4 bytes).
• Temperature, ºC (4 bytes).
The size of the sent data block is 30 bytes.
