Crane Control Module (CCM)
CCMs are controllers that run the software programs
governing crane operations in the rotating bed and car body.
The software running in each CCM controls the I/O devices
connected directly to the CCM and any I/O modules
connected to its bus.
There are three CCMs mounted on the crane (see
Figure 3-7
):
• MWCCM-10 (1) (rotating bed—master)
• MWCCMC11 (2) (rotating bed—slave)
• MWCCMB11 (3) (carbody)
