acd

Purpose

This example shows the acd (Address Conflict Detection) implementation for Ethernet/IP.

Configuration

The IP 192.168.1.12 is set by default

The acd for Ethernet/IP configuration is following:

Usage Hints

This example shows how to use acd.

Whether ACD is activated can be checked via the TCP / IP Interface Object - Instance Attributes 10 (SelectAcd). This should be on by default. For reasons of compatibility, the acd config variable must also be set in addition to the SelectAcd attribute.

goal_eipCfgAcdOn(GOAL_TRUE);

During / after the probe process of the IP address, goal_ipProbedCbis called and it is reported whether the probe process was successful (GOAL_ACD_CB_IP_PROBED) or not (GOAL_ACD_CB_IP_CONFLICT).

If a conflict occurs, information is given at which phase (GOAL_ACD_PROBE_IPV4_ADDRESS, GOAL_ACD_ONGOING_DETECTION, GOAL_ACD_SEMI_ACTIVE_PROBE) in the probe process the conflict occurred.

The IP address is only ready for use after the probe process has been successful.

If a conflict was detected, the conflict packet can be read out via TCP / IP Interface Object - Instance Attributes 11 (LastConflictDetected) after a reboot. A reboot is necessary because the device gives up its IP address in the event of a conflict.

mctc_ac

Purpose

This module provides a simple micro core to core application using GOAL. This application is used for AC and CC. The application handles cyclic data for the MCTC communication. They contain a local time stamp and an incremental transmission counter, which are transfer to the peer core. Meanwhile, the other core do the same.

Configuration

Usage Hints

The content of received data is compared to the content of the next cyclic data, for determining the delay of communication.

see Micro Core to Core - User Manual

mctc_ac

Purpose

This module provides a simple micro core to core application using GOAL. This application is used for AC and CC. The application handles cyclic data for the MCTC communication. They contain a local time stamp and an incremental transmission counter, which are transfer to the peer core. Meanwhile, the other core do the same.

Configuration

Usage Hints

The content of received data is compared to the content of the next cyclic data, for determining the delay of communication.

spi

Purpose

This module provides a simple SPI test for both master and slave. The SPI mode (master/slave) is auto detected by values stored in the SPI MA.

Configuration

Usage Hints

The master cyclically sends out data generated by a deterministic function based on the last data sent. The slaves mirrors the data as soon as possible. The deterministic function should be bijective - that means to each argument there is exactly one image and vice versa. Both sides check received data for correctness. The slave directly checks if the alogorthm applied to last master data received leads to current received data. The master checks if the algorithm aplied to received data (zero, one or more times) leads to last sent data. In this case the number of algorithm calls corresponds to the number of SPI frames between master message and slave answer.
