How do I connect an Allen-Bradley SLC processor to a SEPAM 2000 device?
The MVI46-MCM will provide Modbus in the SLC chassis for connection to the Sepam 2000....
Read moreCan the ProSoft SLC communication modules be placed in a remote SLC rack?
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....
Read moreIs 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 ...
Read moreMy 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...
Read moreWhat 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...
Read moreCan 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....
Read moreWhen 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...
Read moreFloating Points
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...
Read moreHow 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...
Read moreHow do you setup the Pass-Through port on a MVI46-DFNT? Can you program through the Pass-Through port?
Yes, you can program the SLC processor when in DF1 pass-through mode. Please see the User Manual for the specific ProSoft solution you have for more information....
Read moreHow can I store my RSLogix500 program in a M13 EEPROM installed in a ProSoft 3250-L532M SLC processor?
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 (A-B) M11 and M12 EEPROMs. However, ...
Read moreWhen trying to configure my MVI module in RSLogix500, the Input and Output Image size parameters are greyed out.
RSLogix 500 MVI version 5.5 of RSLogix 500 contains a bug which greys out these selections for specialty I/O modules. You will need to contact Allen-Bradley to upgrade your RSLogix 500 software....

Read moreWhat is the difference on the MVI46 module from F/W revision 1.02 to 1.03?
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...
Read moreI 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 ...
Read moreWhere is the configuration stored on the MVI46, 56, 69 and 71 modules?
Q: I've read where it states that the battery is backup power for the CMOS. Is this where all the PCB configuration is stored or do the modules have ROM memory for the PCB configuration?A: With all the MVI46, 56 and 71 modules, configuration is either stored in CF, o...
