7.19 Miscellaneous Block - Communications
The Communication parameters control the 'Modbus' serial port
interface available at CN16 (DB9) and TB2 (terminal strip).
Network Address (434)
The
Network Address
is used to distinguish one device
on the network from others. Each device on a Modbus
network must have a different address.
Baud Rate (435)
This parameter sets the transmit and receive rate of data over the serial communications
port. All devices on the network should be set to the same value.
Parity (436)
The
Parity
parameter sets the type of byte level error checking that is used. All devices on
the network should be set to the same value.
Stop Bits (437)
Sets the number of stop bits used per byte. Normally, all devices on the network should be
set to the same value. In the Modbus specification, the number of stop bits is determined by
the parity selection. One stop bit should be used with Even or Odd parity, and two stop bits
should be used with No parity. However, at very high baud rates, like 38400, Carotron
recommends that the Stop Bits setting in the master be set to two stop bits regardless of the
setting in the Elite Pro or other slave devices. The extra stop bit sent from the master will not
cause any communications errors (even if the other slave devices are set to one stop bit), but
may help the master establish communication with all devices on the network.
