Safety Control Module (SCM)
SCM is a controller that runs the software programs to
interface with the cab controls and to govern boom and jib
load safety. The software running in each SCM controls the
I/O devices connected directly to the SCM and any I/O
modules connected to its bus.
Crane Control Module (CCM)
CCM controllers run the software programs governing the
crane operations. 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 two CCMs mounted on the crane (see Figure 3-7
):
• CCM-10 (1) (rotating bed—master)
• CCMC11 (2) (rotating bed—slave)
