How do I deal with an unsigned integer in an SLC, PLC5, or MicroLogix processor?
Viewed 1 times since Tue, Jan 23, 2007
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... Read More

Connect PC to module's debug / configuration port using a null-modem cable Start Hyperterminal, Putty or other comm program and use the following settings: bits per second: 57,600 data bits: 8 parity:... Read More
When 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.
Viewed 1 times since Tue, Nov 28, 2006
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,... Read More
Is there a limit to the number of ProSoft modules I can place in my SLC chassis?
Viewed 1 times since Tue, Nov 28, 2006
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... Read More
What are the advantages of the MVI46-MCM compare to the 3150-MCM?
Viewed 1 times since Tue, Nov 28, 2006
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... Read More
My MVI46 module faults the processor after cycling power to the rack.
Viewed 1 times since Tue, Nov 28, 2006
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.... Read More
Can the MVI46 or 3150 modules be placed in a remote rack?
Viewed 1 times since Tue, Nov 28, 2006
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. Read More

How can I store my RSLogix500 program in a M13 EEPROM installed in a ProSoft 3250-L532M SLC processor?
Viewed 1 times since Wed, Dec 3, 2008
Before answering that question, a little history lesson will help understand the issue and the suggested solution. The ProSoft 3250-L532M SLC 5/03 RTU processor's operating system (OS) firmware is 100% compatible only with Allen-Bradley's ... Read More
I 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?
Viewed 1 times since Fri, Oct 31, 2008
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... Read More
How to enable Modbus commands in MVI46-MNETC
Viewed 1 times since Wed, Sep 24, 2014
MNETC and MBTCP products use a bit array to each command in each client. In the case of the MVI46-MNETC, each 16 bit register in N50:21 through N50-50 of our sample logic contains the bits to enable or disable the 16 available commands in the 30... Read More
