Purpose
The purpose of a mhttpd MSCB Page is to visually present the devices in the MSCB (MIDAS Slow Control Bus) system and their variables.
Access to the MSCB Page
The MSCB Page is displayed by clicking on the MSCB button on the mhttpd Status Page or other mhttpd web page.
- Note
- If the MSCB button is not present on the Status Page, either
- MIDAS has been built without MSCB support (see below) or
- it may have been suppressed.
MIDAS with MSCB support
In order to create the MSCB page, the flag
- -DHAVE_MSCB
must be present in the MIDAS Makefile so that mhttpd is linked against ../mscb/mscb.c and has direct access to all mscb ethernet submasters (USB access is currently disabled on purpose there). The presence of the flag -DHAVE_MSCB will cause the MSCB button to appear on the Status Page by default, unless the menu button has been suppressed.
Features of the MSCB page

The MSCB page (see Figure 1) displays information from the /MSCB ODB tree. It obtains a list of all available submasters from the Submaster subtree.
The Rescan button will rescan the MSCB devices, the Reload button refreshes the page.
