HI 800 101 HIMatrix Engineering Manual
5.3 Field Bus Communication
The controllers F20, F30, F35 and the CPU of the modular system can be equipped with
modules for field bus communication (Modbus, Profibus, Interbus).
Four intern pluggable communication modules are available. These supplement the existing
field bus interface with the following functions:
• HIMA CM-PROFIBUS-DP master
• HIMA CM-PROFIBUS-DP slave
• HIMA CM-RS485 (as MODBUS master or MODBUS slave configurable)
• HIMA CM-INTERBUS master
With the mentioned communication modules the field bus interfaces of FB1 and FB2 of the
HIMatrix controllers F30, F35, F60, at F20 only FB1, can be equipped. Without communi-
cation module the field bus interfaces FB1 and FB2 are not functional.
Note
The mounting of the communication modules is only permitted by
HIMA, otherwise the guarantee of the controller will be nullified.
No unlock code is necessary for unlocking a communication module at Profibus and Inter-
bus.
For Modbus you need a license and get the unlocking code via homepage.
5.3.1 Restrictions for simultaneous Operation of Protocols
PROFIBUS-DP master or slave can only be used on one field bus interface, i.e. two
Profibus master or slaves at one time in one resource are not supported and will not func-
tion.
MODBUS master/slave RS485 will only run on one field bus interface. An operation via
RS485 and Ethernet simultaneously however is possible.
An INTERBUS master will only run on one field bus interface.
Note
Safety-related communication is not possible with the field bus
interfaces.
The communication unit with the field bus interfaces is connected to the safe microprocessor
system via a Dual-Port RAM. Only devices with a safe electrical isolation may be connected
to the interfaces.
Note
The communication modules CM-PROFIBUS-DP master and
CM-INTERBUS can be used on controllers F20, F30, F35 or F60
as of hardware revision 02.
