What causes a conditional command to be issued?
A conditional command is useful when the same value does not need to be written to the end device continuously, but rather on change. A conditional write command is scanned based upon its poll rate (like all other commands). The difference is that it will not be execut...
Erfahren Sie mehrWhat does a -36 modbus error code indicate?
A negative thirty six (-36) error code is generated when we have successfully connected to a device and issued the device a Modbus request, but it has not responded to the request within the defined response time out period. This is akin to calling some one on the phone, having s...

You can initialize the input data (ReadData) with cached values from the processor on these In-Chassis modules so that these values do not get reset to 0 during a module reset or powerloss. To do this the parameter labeled "Initialize Input Image" or "Initialize Ou...
Erfahren Sie mehrWhich ProSoft products can communicate with a Honeywell DCS System?
Most Honeywell DCS Systems support either Serial Modbus or Modbus TCP communication. If your application involves Rockwell Automation PACs or PLCs than consider one of our In-Chassis modules such as the MVI56E-MCM or the MVI56E-MNET. If the application is using anothe...

This error is indicative of a backplane issue between the prosoft card and the compact logix PLC.With the MVI69E and MVI69L modbus modules, all of the configuration is stored on the PLC itself, not on the Prosoft card. This means that, unlike with some of our other modules, it is...

Some Prosoft modules, such as the 69E and 69L families, have only the option to use CIP Connect over the backplane for configuration downloads and uploads in the Prosoft Configuration Builder (PCB). Other modules offer CIP Connect as an alternative to connecting directly to the c...
