AC500CS31 communication

CS31 fieldbus features

Communication: RS485 ( twisted pair, with shield)

Protocol: CS31 (Master / Slave)

Number slave units: maximal 31 modules

Maximal length: 500 m (2000 m by repeaters 3x NCB)

Bus redundancy: by bus repeater NCBR

Transmission rate: 187.5 KBaud

AC500CS31 Field Bus

CS31 fieldbus rules

The slaves are identified by a module address between 0 to 61.

The module address should be reported inside AC500 control builder software PS501 in function of hardware configuration units present on CS31 bus.

The master AC500 can manage up to 31 module addresses.

- Example of one module address:

A series 30 or 90 remote units

An ICMK14 remote unit with binary extensions

An DC551 remote unit with binary I/O bus

A central unit ( 50 series with extensions, 90 or 30 series )

Warning : DC551 remote unit with analog I/O bus could use up to 6 module addresses.

CS31 fieldbus I/O addressing

The structure of I/O addressing is based on Byte format (modulo 8) even if remote units have more than 8 channels (07DI92) or less than 8 channels (XK08F1). With respect to the MOTOROLA Byte order.

The module address number doesn’t appear anymore in structure of CS31 I/O Variables. Following the configuration, AC500 control builder software creates and optimizes automatically the addressing of variables

Specific variables area for COM1:% IB1000 ……. % IB1999% IW500 …...... % IW 999% ID250 ……… % ID499

Same relation for outputs Q % IX1000.0 ….. % IX1999.7
