Overview

Communication Description

processor/module

MODBUS Due to its high dissemination, this protocol offers connectivity for controllers of dif fe-

rent origin, to operating panels and PC operating stations. The MOD BUS interface(s)

is integrated in the CPU. A further MODBUS coupler with 2 additional interfaces can

be attached.

Max. number of particpants with RS 485: 32. Max distance with RS 485: 1.2 km.

Possibility for connecting a user-to-user modems. Net work de sign: Point-to-point and

multipoint-line.

Ethernet Supports sending and receiving data via TCP/IP and/or UDP/IP. Further application

layers can be implemented by download. It is even possible to run TCP/IP, UDP/IP

and application layers simultaneously. The protocols: IP, TCP, UDP, ARP, RP, BOOTP,

DHCP are supported as standard. A communication with third-party-systems is

possible using either MODBUS/TCP or customer speciﬁc applications lay ers. Transfer

rate 10 / 100 Mbit/s.

CANopen Standardised layer-7-protocol on the basis of Controller Area Network (CAN) and of

the CAN application layer (CAL). The access method is based on the master-slave-

principal. It allows for the combined operation of several busmasters as well as the

synchronized data transmission to multiple subscribers and up to 2.048 different com-

munication objects. Baud rate of up to 1 Mbit/s.

Protocols: event-triggerd, cyclical, acyclical, on demand.

PROFIBUS DP Allows for the master-and-slave communication in the ﬁeld.

Connection to automation systems of third-party manufacturers as well as intelligent

preprocessors like drives, control panels and sensors.

Max. lenght of the net (RS 485): 1200 m at 9.6 kBit/s. 32 stations per net max

(master and slave). 126 with repeater. Transfer rate 9,6 kBit/s up to 12 MBit/s.

ARCNET is the basis for an economical and fast integration of AC31 progammable controllers.

Also suited for the process visualisation or for connection of other systems.

Data trans fer rate of 2.5 MBit/s. Collision free data transfer due to token bus with

automated lo gin and logoff of participants. Automated reconﬁguration of the net when a

station ac tivates or deactivates.

Up to 255 masters on the same net.

Overall net lenght 300 m, up to 6 km with repeaters . All net forms e. g. net, star.

RCOM is a communication protocol designed for the remote data transmisson. It is suited

for transmissions using a user-to-user or dial-up connection.

Standard modems establish the connection between stations.

DeviceNet For fast data exchange on the ﬁeld level. For coupling of decentral ﬁeld devices

like I/O, drives and valves.

CS31 Bus for the easy connection of CPUs and I/O devices . The CS31 system bus is

a RS 485-2-wire bus, designed for a fast and interference resistant data transfer. Up

to 31 I/O-devices.

Max. lenght: 500 m resp. 2000 m with repeater. With repeaters you can also achieve

bus redundancy. Transfer rate: 187.5 KBaud.

AC31 Safety-Fieldbus For the certiﬁed transmission of safety signals bet ween safety-related con trollers and

the safety-related I/O devices (AC31-S only). Mixing of safety-related signals and ope-

ration signals
