No, the 3150 and MVI46 line of ProSoft modules can only reside in the local SLC rack, or an extended SLC rack. If serial communications is necessary at a Remote I/O location, then the ProLinx 4601-RIO module should be considered....
Lire la suiteIs there a limit to the number of ProSoft modules I can place in my SLC chassis?
There are limits to the number of ProSoft modules that can be placed in your system's rack:1. The number of available slots in the chassis.2. The size of the power supply used for the chassis; specifically, how much 5vdc current is available. Each ProSoft module will ...
Lire la suiteMy MVI46 module faults the processor after cycling power to the rack.
The bios settings have the console enabled. This will cause the MVI46 module to send a series of printf's out the debug port. This does not allow the module to boot up fast enough for the processor, and this will in turn fault the processor. By disabling the console setting in...
Lire la suiteWhat are the advantages of the MVI46-MCM compare to the 3150-MCM?
Here are some of the main advantages of the MVI46-MCM over the 3150-MCM: Direct M0/M1 file access, makes it much easier to configure You do not need to page memory as the 3150-MCM supports baud rates to 115.2 (3150 only to 38.4) 100 Modbus master commands on each port (200 to...
Lire la suiteCan the MVI46 or 3150 modules be placed in a remote rack?
No. The MVI46 and 3150 module can only reside in the local or extended rack. Many times a ProLinx 4601-RIO-MCM can work in this type of application. The usage of M1 and M0 files prevents the module from operating in a remote rack....
Lire la suiteWhen using the sample ladder I get an M0/M1 file reference error in my SLC processor if the MVI46 or 3150 is not in Slot 1.
The M0 and M1 files are slot referenced. The second digit in the address represents the slot number. If the MVI46 or 3150 module is in slot 1 (next to the processor), then the file reference is M0:1.XXXX and M1:1.XXXX If the module is in slot 5, then the file reference would b...

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 suiteHow do I deal with an unsigned integer in an SLC, PLC5, or MicroLogix processor?
Scenario: A device that uses an INT value to represent a range of 0 to 65535, but in the processor the INT tag has a range of -32768 to 32767.Since the A/B processor does not have an unsigned Integer data type, you will need to convert this value to represent the full range. Simp...

MVI46 Ethernet modules updated from firmware revision 1.02 to 1.03 in 11/2004, ECN 572 addressed an issue that was discovered with all Ethernet versions of the MVI46 module. There was a timing issue between the MVI46 module and the Ethernet daughter card. This required a reprogra...
Lire la suiteI am using a ProSoft MVI46 solution and I am getting a Fault Message that says, "Specialty I/O Module in Slot x has not responded within the time limit." What can cause this?
This particular fault is infrequent but common on the SLC platform. Without getting into a lot of boring details, it has to do with critical, sub-millisecond timing of backplane messages. ProSoft has worked closely with Rockwell Automation to minimize to the greatest ...
