Crane Control Module (CCM)
CCMs are controllers that run the software programs
governing crane operations in the rotating bed and carbody.
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
(Figure 3-7
):
• MWCCMB11 (carbody)
• MWCCM-10 (rotating bed—master)
• MWCCMC11 (rotating bed—slave)
