Router

Info

Router 1:

Memory

The displayed RAM is required in the TwinCAT system for AMS messages and for memory management in the TwinCAT real-time environment. The entire memory is requested by Windows when the TwinCAT system starts up. The memory size can be configured in the TwinCAT system node.

Over all

RAM that was available when the TwinCAT system was started.

Available

RAM that is currently available for TwinCAT.

Registered

All devices taking part in the TwinCAT messaging system (AMS) have to register with the router. TwinCAT servers have fixed port numbers (e.g. TwinCAT PLC LZS1: 851, …). TwinCAT clients are assigned a port number by the message router.

Mail debugging

In conjunction with the TwinCAT ADS Monitor, the whole TwinCAT message traffic can be logged. Note that the message traffic is slowed down by the additional messages. The TwinCAT ADS Monitor is not part of the standard scope of supply of TwinCAT.

Cleanup

The cleanup function of the router can be used to release router ports originating from programs that are no longer functional. This function is particularly useful in the development phase of PLC projects.

Changing the AMS NetID

Router 2:

Local computer

AMS NetID

The AMS Net ID is the address of the local computer in the TwinCAT network. The AMS Net ID consists of 6 bytes and is represented in a dot notation. The “Net IDs” must be assigned by the project planner and must not be repeated in the TwinCAT network. By default, the installation generates an AMS NetID from the IP address of the system (if available) + “1.1”. If no IP address can be determined during the installation, the AMS NetID “1.1.1.1.1.1” is created.

Editing routes

The TwinCAT Static Routes dialog shows all the route information of the local TwinCAT system.

The Add button can be used to add new routes.
