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.  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

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... Read More

The type mismatch error is always shown since the ProSoft In-Chassis modules do not support the additional functionality required to respond to this inquiry from the processor.  This field does not reflect the status of the ProSoft In-Chassis... Read More

Confirm that the Comm Format parameter in the modules I/O configuration is set to Data - INT. The default setting for this parameter in RSLogix5000 is Data - DINT. This setting will generate the error message mentioned above. If the incorrect... Read More

The heat dissipation for MVI56, MVI56E, MVI69, MVI46 and MVI71modules is as follows: The power ratings label states that the maximum current drawn from the ControlLogix backplane is 800 ma at 5.1 VDC, 4.08 watts. If you want to convert this to BTU... Read More

The battery is integral, rechargeable, and soldered to the main board of the module. The on-board battery is not user-serviceable. The purpose of the battery on the MVI module is to maintain the BIOS settings which are checked during the boot up... Read More

The GSV (get system value) instruction in RSLogix 5000 can retrieve the status of the communication or I/O modules.  The required parameters for GSV are: class name module instance name module name in the I/O configuration ... Read More

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. ... Read More

The backplane current draw for modules in these series is 800mA at 5.1VDC. Additionally, MVI69 modules are required to be within two slots of a power supply on the 1769 bus. Read More

Optional AOIs, are, as their name suggests, Add-On Instructions which are not necessary for the operation of their corresponding card. For most applications, they are completely unnecessary, as the only features they provide are the ability to... Read More

When Rockwell Automation released Version 16 (and later) revisions of RSLogix5000 programming software for ControlLogix systems, they had to change the starting point of the timebase for the processor's internal clock and added some new features... Read More

Using the following configuration: ·         - RSLogix 5000 Version 18 ·         - A ControlNet Network is implemented in the project.... Read More

99.61% represents the allowable ControlNet bandwidth. The bandwidth rule is that each scheduled node gets 1 and only 1 opportunity to talk during the scheduled portion of a NUT (Network Update Time). The maximum amount of data that any node can... Read More
