LM P RS485 Data Logger
7.3
DADR
(D
EVICE ADDRESS
)
➢
Address range of the devices that can be connected for MODBUS RS485
communication is from 1-247.
➢
To set device address follow the steps given below by pressing the appropriate
buttons given on the front panel of the Device.
➢
To set the Device address, follow the procedure shown in figure 29.
7.4
PRTY
(P
ARITY
)
➢
A parity check is the process that ensures accurate data transmission between
devices during communication.
➢
If there are same parity bits in the communication devices, then the devices will
communicate with each other.
➢
E.g. If the pressure device has parity bit odd, then it can only communicate with
the device having odd parity bit, otherwise there is no communication between
them.
➢
Similarly, If the pressure device has parity bit even, then it can only communicate
with the device having even parity bit.
➢
If the pressure device has parity bit none, then it can communicate with the device
having any parity bit (none, even and odd).
➢
To set the Parity, follow the procedure shown in figure 30.
