● Communications Parameters
Changes to the settings are enabled when you return to Measurement Mode.
• Protocol Selection (80.psl)
Select the communications protocol. You can select either CompoWay/F or Modbus.
If Modbus is selected, the data length will always be 8 bits and the number of stop bits will be set
automatically according to the vertical parity.
No vertical parity: 2 bits
Odd or even vertical parity: 1 bit
• Communications Unit Number (81.u.no)
The communications unit number is used to differentiate between different nodes when
communicating from the host. The communications unit number can be set to integers between
0 to 99.
The default setting is 1. If the same communications unit number is set for more than one node,
normal operation will not be possible.
• Baud Rate (82.bps)
Set the baud rate for communications with the host. The baud rate settings are as follows:
1.2 (1.2kbps), 2.4 (2.4kbps), 4.8 (4.8kbps), 9.6 (9.6kbps), 19.2 (19.2kbps), or 38.4 (38.4kbps)
• Data Length (83.len)
Set the communications data bit length. The bit length can be 7 bits or 8 bits.
• Stop Bits (84.sbt)
Set the number of communications stop bits. Either one or two stop bits can be set.
• Vertical Parity (85.prt)
Select the vertical parity. The parity can be set to none, even, or odd.
• Transmission Wait Time (86.sdw)
The transmission wait time can be set to between 0 and 99 ms in 1-ms increments. The default
setting is 20 ms.
