variables)

Connections

2-wire

Max. distance 1000m,

termination directly on the

module

Addresses

247, selectable by means

of the front key-pad

Protocol

MODBUS/JBUS (RTU)

Data (bidirectional)

Dynamic (reading only)

System and phase

variables: see table “List of

variables...”

Static (reading and writing only) All the configuration

parameters.

Data format

1 start bit, 8 data bit, no/

even/odd parity,1 stop bit

Baud-rate

Selectable: 9.6k, 19.2k,

38.4k, 115.2k bit/s

Driver input capability

1/5 unit load. Maximum

160 transceivers on the

same bus.

Note

With the rotary switch

(on the back of the basic

unit) in lock position

the modification of the

programming parameters

and the reset command

by means of the serial

communication is not

allowed anymore. In this

case just the data reading

is allowed.
