Using DeltaV M-Series Virtual IO Modules with S-Series Controllers Without Extenders (FAT ONLY)
The purpose of this application note is to describe how to use DeltaV M-Series VIMs with S-Series Controllers without extender cards and cables (for Factory Acceptance Testing with MiMiC ONLY).
The M-Series DeltaV Virtual IO Module (VIM), VIM-4201, was designed to connect to M-Series carriers. The physical designs of the newer S-Series VIMs and carries have changed which has caused the M-Series VIMs to be incompatable with S-Series Controllers by default. There are currently two workaround solutions to this problem:
Option A: Connect the S-Series Controllers to S-Series carriers and connect M-Series VIMs to M-Series carriers. The S-Series and M-Series carriers are incompatible and cannot be connected directly. The two carriers can be connected together with the use of an S-Series extender card, an M-Series extender card, and an extender cable. This method is covered in more detail here: http://www.mynah.com/knowledge-base/using-deltav-m-series-virtual-io-modules-s-series-controllers.
Option B: The physical connection between the VIM and the carrier did not change between series; therefore, by removing the VIM casing, the M-Series VIM motherboard can connect directly to an S-Series carrier.
This Application Note discusses Option B.
- This procedure should ONLY be used for Factory Acceptance Testing with MiMiC and is absolutely not recommended nor supported for live systems.
- This procedure involves removing the motherboard from the VIM casing. MYNAH Technologies is NOT responsible for any physical damage to the VIM as a result of following the instructions detailed in this Application Note.
- There is a possibility of experiencing intermittent communication issues with this configuration due to the lack of a secure connection that is caused by the removal of the VIM casing. MYNAH Technologies cannot guarantee the same standard of performance from the VIM without the protective casing.
Step 1 - Remove the VIM Faceplate and Pin
The faceplate hooks to the body at the top and bottom. Apply pressure to the top of the faceplate and pull it away from the body to remove.
Step 2 - Gently Remove the VIM Motherboard
You will notice that the motherboard is actually two circuit boards joined together by a single connection located behind the LEDs. This connection must remain secure for VIM communications to function. The VIM casing holds these two boards in place so this connection will be vulnerable as long as the boards are exposed. Try to keep the boards as parallel as possible.
Step 3 - Connect the VIM Motherboard to the S-Series Carrier
Again, use caution when connecting the board to the carrier and when connecting the ethernet cable to the motherboard.
