Exchange Of Signals With Masterdrive Mc / Vc From 1997 / 98 - Siemens SIMOVERT FC Series Operating Instructions Manual

Function Descriptions
b) Control bit 10 ("Control requested")
Control bit 10 should be "wired through" directly from the CBx /SCBx to the basic unit. For this purpose, for
example, bit 10 of K062 [18.3] must be isolated by means of a connector/binector converter and supplied to the
basic unit via H272.11.
With a "1" status of bit 10, the automation system declares all its setpoints and control commands to be valid
and requests the converter to accept them.
Bit 10 is not directly supported on the T100, i.e. the setpoints and control commands from the automation
system which are connected to the T100 are always accepted regardless of bit 10 (but can, of course, be
disabled or enabled on the T100 as a function of bit 10 if required). However, since the basic unit does not
accept any setpoints or control commands at its dual-port RAM as long as the "wired-through" bit 10 is "0", it can
always be guaranteed that no hazardous situations will arise.
c) Status bits 3, 7 and 9
The following status bits should be "wired through" from status word 1 of the basic converter to transmit word 1
of the CBx / SCBx (see [13.7]):
- Bit 3 "Fault" (binector B035)
- Bit 7 "Alarm" (binector B039)
- Bit 9 "Unit requests process data control from automation system" (binector B041)
These binectors should be connected to bits 3, 7 and 9 of the connector which can be selected via H311.1
[18.5], thus ensuring that the communications display word in DVA_S5 is updated.
d) Adjustable length of process data area for PROFIBUS messages (PPOs)
The PROFIBUS profile only permits process data lengths of 2, 6 or 10 words (PPO types 1 to 5).
e) Adjustable length of process data area for USS messages
The length of the process data area for USS messages can be between 0 and 10 words. When the length is "0",
points a) to c) of this section do not apply and bits 6, 7 and 8 of the communications display word in the SIMATIC
are not updated in DVA_S5.
3.8 Exchange of signals with MASTERDRIVES MC / VC from 1997 / 98
The data exchange with the basic unit takes place via a high-speed DUAL PORT RAM located on the T100 (see
sheet 1 of block diagram). A maximum of 10 values in the actual value area can be transferred at a time from the
basic unit to the T100 and in the setpoint area from the T100 to the basic unit. The connection of these data -
both in the basic unit and in the T100 - is shown on sheets 10 ... 14 of the block diagram.
Note: Pages 10 ... 14 of the block diagram show the process data exchange with the Master Drives VC and
MC. Please consult the Operating Instructions of your Master Drives basic unit for details of the
process data interface between the basic unit and technology board ("TB") which is currently available.
The connection of process data exchanged with the T100 in the Master Drives infeed/regenerative
feedback units is not shown in the diagram. These connections must be made on the same basis as
the mechanisms described in this manual in accordance with the operating instructions of the
input/regenerative feedback unit used.
Actual value area (signals from basic unit ⇒ T100)
It is possible to link any connectors of the basic unit to the words in the actual value area by means of
P734.01...10.
Example: - Basic unit is a MASTER DRIVE VC
- The actual frequency value KK151 must be linked to the T100 in word 2 of the actual value area
- ⇒ Set P734.02=151!
- The actual frequency value is available in K038
