6.4.2 Results output via field bus
6.4.2.1 Configuration of the field bus interface
The required communication parameters are configured via the interface configuration.
To configure the field bus interface of the CS351 compact system:
1. In the BS350 operating system, click System Tightening channel configuration.
This function calls up the current configuration of a tightening channel.
2. Double click the line CS to view the interfaces.
3. Double click the line A to open the associated parameters dialog.
4. At Code, select the interface module and enter the required parameters, see section Setting up
additional interfaces from page 561.
To configure the field bus interface of the KE350 communication unit:
1. In the BS350 operating system, click System KE configuration.
This function opens the KE configuration currently on the controller.
2. Double click the line A to open the associated parameters dialog.
3. At Code, select the interface module and enter the required parameters, see section Setting up
additional interfaces from page 588.
6.4.2.2 Sending the configuration to the tightening system
The interface configuration is only valid after the settings have been sent to the tightening system.
6.4.2.3 Testing the connection to the partner controller
The LEDs on the interface modules communicate information on the connection status and whether the
module is ready-to-operate. For further information, refer to the individual instructions of the interface
modules.
If the connection is not functioning at the point when the results are output via field bus, a class 1 or 3
error will be generated (page 309).
The System test
KE field bus data… or System test CS field bus data … can be used to display
and analyze the contents of the storage areas on the interface module. With this, you can check in the
BS350 operating system whether an ID code has been correctly transmitted or whether a results value
has been properly configured.
6.4.3 Transferring the ID codes to the tightening system via field bus
The ID code is transferred by the field bus master to the data buffer of the field bus interface as a character
string (ASCII) (see Table 6–45: Allocation of the data buffer for IMpdp (page 291), Table 6–46:
Allocation of the data buffer for IMdev, IMmtcp, IMenip and IMenip2 (page 291), Table 6–47: Allocation
of the data buffer for IMecat (page 291) and Table 6–48: Allocation of the data buffer for IMpnio and
IMpnio2 (page 291)).
To activate the field bus ID-code source:
Go to System Tightening cell data
ID Code and select Field bus as ID code source.
An ID code that is transferred to the IMpdp interface module / in the control unit of channel x.y, is used
for the next tightening process (started with CH x.y CW or CH x.y CCW). The ID code must be stored in
the data input field 100 ms before starting the tightening and remain stored until the end of tightening
(CH x.y CyCmp, FO x CyCmp).
