Control of the
AF 100 Link
The AF 100 link provides communication between multiple AC 80
stations. AF 100 is also used for connecting one or several AC 80 units
to an external system (such as the AC 110 controller), or for connecting
the AC 80 to an APC2.
Addressing The address for the AC 80 station on the AF 100 link is given in the DB
section of the application program. The node (station) number of the
AC 80 is defined by the AF 100 part of the DB element PM825. The
terminal named STNNO, in the AF 100 part, is used for setting the
station number. Its value must match the hardware address setting of
the AC 80.
Figure 4-22 The terminal settings of the AF 100 part of the PM825
database element.
The CABLE terminal should be set to S (for single-cable bus
connection) or to R (for redundant cabling).
The TIMESYNC terminal should be set to MASTER on one station on
the AF 100. All other stations should be set to SLAVE (or NONE, if
synchronisation is not required).
Communication
between Advant
Controllers
For the PC section of the application program, the following elements
are available: AFREC or MB90REC and AFTRA and MB90TRA.
For AF 100 communication with an APC2 system, see the manual
Function Blocks for APC2.
DB Elements
The PM825 DB element is the only one needed for AF 100
communication. See above, and the section
The PM825 Element
(page 4-1).
The DSP (DataSet Peripheral) element is used for removing error code
3106 from the error terminal (ERR) of MB90TRA/MB90REC. Without
the DSP element, the communication will work but the system will
produce an error code.
