MOTOROLA MVME5500 Control card

RS-232 Configuration/Debug Port This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is included with the module. This port permits a PC-based terminal emulation program to view configuration and status data in the module and to control the module. The cable pinout for communications on this port is shown in the following diagram.

If you see the status as running, you will not be able to use this com port for anything other than communication to the processor.When you have verified that the driver is not being browsed, go to COMMUNICATIONS > CONFIGURE DRIVERS.

Note: You may need to shut down and restart your PC before it will allow you to stop the driver (usually only on Windows NT machines). If you have followed all of the above steps, and it will not stop the driver, then make sure you do not have RSLogix open. If RSLogix is not open, and you still cannot stop the driver, then reboot your PC.

Disabling the RSLinx Driver for the Com Port on the PC

 The communication port driver in RSLinx can occasionally prevent other applications from using the PC’s COM port. If you are not able to connect to the module’s configuration/debug port using ProSoft Configuration Builder (PCB), HyperTerminal or another terminal emulator, follow these steps to disable the RSLinx driver. 1 Open RSLinx and go to COMMUNICATIONS > RSWHO. 2 Make sure that you are not actively browsing using the driver that you wish to stop. The following shows an actively browsed network.3 Notice how the DF1 driver is opened, and the driver is looking for a processor on node 1. If the network is being browsed, then you will not be able to stop this driver.

MVI46-MNETC Status Data Definition

 This section contains a description of the members present in the status data object. This data is transferred from the module to the processor as part of the read data area when the block transfer interface is used.

This value is incremented each time a complete program cycle occurs in the module.This field contains the total number of read blocks transferred from the module to the processor.This field contains the total number of write blocks transferred from the processor to the module.This field contains the total number of blocks successfully parsed that were received from the processor.This field contains the total number of command event blocks received from the processor
