Lire la suiteWhy do I have a yellow question mark in the RSWho window or in RSNetworx for my MVI56 Series module?
If you have a yellow question mark in RSLinx's RSWho window, or in the RSNetworx window it is usually due to not having the EDS file registered for the MVI56 Series modules. ...
Lire la suiteCan the MVI56-xx modules be placed in a remote rack?
Generally, yes. When using ControlNet to access the remote chassis, however, I/O bandwidth limitation may become an issue.Because the MVI56 modules requires 250 words of inputs, and 248 words of output, the ControlNet bandwidth may not be sufficient to handle this depending on th...
Lire la suiteWhat is the best way to monitor the "health" of my MVI56 module?
The controller tag local:(slot #):i.data[249] is the best indication of the module communicating with the CLX processor. If this value is not changing then the module has stopped for some reason.Related Keywords:MVI56...

Lire la suiteWhat is the purpose of the last 4 branches of Rung 1 of Start/Power Up?
These branches have no purpose in normal operation. However, if it is necessary to write a string longer than 200 characters write-wait logic will have to be added to the ladder. In that case the 4 branches would be involved.As there is no write-wait logic in our sample ladder th...

Floating point numbers (also known as 'real numbers') give a certain freedom in being able to represent both very large and very small numbers in the confines of a 32 bit word (that's a double word in our PLCs). Up until this point the range of numbers we were able to represent w...

Lire la suiteIn past applications, I've used a 1756-MVI to read from a barcode scanner. Is your MVI56-ADM product similar?
Yes, the MVI56-ADM is essentially the same product as the 1756-MVI. One thing to note, for simple ASCII communications, such as reading/writing to a scale, barcode scanner, serial printer, etc. we strongly recommend you consider the MVI56-GSC....

Lire la suiteHow does the MVI56MCM module work in a Redundant Control Logix Setup?
Since all I/O modules in a redundant ControlLogix application must reside in the remote rack, the ProSoft MVI56MCMR(r) modules must also reside in those same remote I/O racks. As far as the ControlLogix processor is concerned, all MVI56 modules are just an I/O module. For the MVI...

Lire la suiteCan the MVI56-WA-EIP be used to acquire I/O data from a ControlLogix CPU from a remote rack?
The MVI56-WA-EIP must be installed in a chassis that also has a ControlLogix processor installed. It will not function in a chassis that is loaded only with I/O modules. Thus you can use two MVI56-WA-EIP modules to move data between two processors.However, you cannot use a MVI56-...
