Serial Link Via Fieldbus - ABB DCS 500B Description

• Serial link via
FIELDBUS
DCS 500 Software Description
If analog and digital signals are not sufficient for the control or the
status of the drive a serial link based on serial communication mod-
ules may be a possibility to imcrease the number of information or
the accurracy of the signals. The type of module is activated by
means of the block FIELDBUS. The data transferred from the con-
trol to the converter are stored in the blocks DATASET 1 and 3 as a
16-bit-information. Depending on the application the output pins of
these blocks have to be connected to input pins of other blocks in
order to transport the message. The same procedure is valid for
blocks DATASET 2 and 4, if they are connected. These blocks are
transmitting information from the converter to the control system.
There are several different communication adapter available:
- NPBA-02 for serial links, based on PROFIBUS
- NCSA-01 for serial link to ABB PLC type CS31 / AC31
- NMBA-01 for serial link , based on MODBUS
- NMBP-01 for serial link , based on MODBUS PLUS
- FCI for serial link to ABB PLC via AF100 bus
- no module for serial link to ABB PLC type AC70
General: please refer to the documentation describing the serial
link module and the Description of the drive-specific se-
rial link interconnections
Some of these modules have been updated in the past. They are
available with different software versions. The next table shows the
compatibillity (modules marked with * should be used together with
this converter software):
- NPBA-02; software version 2.1
- NPBA-02; software version 2.2 *
- NCSA-01; software version 1.5 *
NMBA-01; software version 1.5 * (supports multilink)
-
NMBP-01; software version 1.5 * (no parameter exchange)
-
- FCI; software version 1.3 *
- AC70; software version 1.1-1 *
