Modbus Address – Click in “Modbus address” to enter a modbus address for
the compressor modbus communications on the RS485 port. The address may
be between 1 and 247. This change takes affect after the controller power is
cycled off and on.
Baud Rate – The rate of data transmission in bits per second. The overall range
is 1200 to 57,600 baud. The default baud rate is 19200 bps.
Parity – Data checking method for verifying accuracy of data transmission.
Parity options for data checking are odd, even, none. The default setting is
“Even.”
3.8.7 Internet Transmission Settings
Some controllers may be configured to allow access and transmission of data via
the internet. These settings have no effect on standard controllers. The TCP/IP
parameters are:
IP Address – The unique address the WSPC will use to identify and
communicate with another computer via the internet or other network utilizing the
Internet Protocol standard.
Net Mask – used to determine what subnet an IP address belongs to.
NOTE
The Modbus settings assigned here must match the modbus settings
assigned in the WSPC User Profile or other Modbus applications. If the
settings do not match, communication with the controller will be lost
when the controller is cycled.
