• Input/Output—Small (IOS)
Control modules are named in the format MWXXXABC.
Table 3-1 defines the variables used to build the name.
Table 3-1. Control Module Naming Definitions
Control Module Input/Output (I/O) Types
Table 3-2 defines the terms used in the schematics for the I/
O types used by the control modules.
Table 3-2. Control Module I/O Types
Safety Control Module (SCM)
The SCM controller runs the software programs to interface
with the cab controls and to govern boom and jib load safety.
The software running in the SCM controls the I/O devices
connected directly to the SCM and any I/O modules
connected to its bus.
There is one SCM mounted on the crane (see Figure 3-6 ):
• SCM-00 located in the right operator cab.
Crane Control Module (CCM)
The CCM controller runs the software programs governing
the crane operations. The software running in the CCM
controls the I/O devices connected directly to the CCM and
any I/O modules connected to its bus.
There is one CCM mounted on the crane (see Figure 3-6 ):
• CCM-10 located in the right enclosure on the rotating
bed.
Input/Output—Large (IOL) Module
I O L s c o n t r o l t h e d e v i c e s c o n n e c t e d t o t h e m a n d
communicate with the SCM or CCM connected to their bus.
IOLs have twice the device capacity as the input/output—
small (IOS) modules.
There are three IOL modules mounted on the crane (see
Figure 3-6 ):
• IOLC30, IOLC31, and IOLC32 located in the right and
left enclosures on the rotating bed.
Input/Output—Small (IOS) Module
I O S s c o n t r o l t h e d e v i c e s c o n n e c t e d t o t h e m a n d
communicate with CSMs or CCMs connected to their bus.
IOSs have half the device capacity as the input/output—
large (IOL) modules.
There is one IOS module on the crane (see Figure 3-6 ):
• IOSA22 located in the operator cab.
