User parameters for the Coupler Box Modules (IL230x-B31x)

DPV1 Services

The DPV1 services can be activated or deactivated here. Default: Not active (see DPV1 services).

Behavior in the event of an IP-Link error

The IP-Link can start up again of its own accord once an IP-Link error (such as a cable break) has been corrected. Warning: PROFIBUS data communication begins once more, and outputs are written again. The user must ensure that undesirable outputs are not written in such a case. Default: Manual reset.

Fieldbus Box Diagnostics

The diagnostic data can be activated here. Default: Not active (see Diagnostics for the Compact Box or Diagnostics for the Coupler Box).
Byte 7, bit 1: 
- True activated
- False deactivated

Data format

Data that is 2 bytes in size can be transmitted either in Intel or in Motorola format. The high byte and the low byte are swapped. Default: Motorola.

Updating process data

The IP-Link can be triggered in synchronism with PROFIBUS , or can be allowed to run free. Default: Free running (see Updating process data).

Reaction to PROFIBUS errors

This describes the behavior of the slave in the presence of a PROFIBUS error (such as a faulty cable). Default: The IP-Link cycle is abandoned

  • The IP-Link cycle is abandoned, which means that the extension module's watchdog will trigger after 100 ms, and the outputs will be switched into a safe condition
  • The IP-Link master writes a 0 to the outputs
  • The outputs remain frozen in their last state

Reaction to IP-Link errors

This describes the behavior of the slave in the presence of an IP-Link error (such as a faulty cable). Default: DataExchange is abandoned

  • DataExchange is abandoned, which means that the slave halts the PROFIBUS communication.
  • DP inputs become 0 - A zero is written to the inputs
  • DP inputs are retained - The inputs retain their most recent valid state

IL/IE Byte Alignment    )1

This allows all the IL/IE23xx modules with 4 bit input/outputs to be rounded to a byte.

Byte 10 bit 5 Default "0"
1    All the IE23xx modules are mapped with eight bits. In fact the inputs from 0..3 are sufficient (4..7 are not used), as are the outputs from bits 4..7 (0..3 are not used).
0    All IE23xx modules are mapped with four inputs and four outputs (default)

)1Firmware update is possible for the IL modules from software version 1 D:xxxx1xxx.
