This parameter shows the status of the Second Processor in the Inter-option module
synchronization scheme. For more information refer to Chapter 10 Inter-option
Synchronization on page 104
Pr 91.22 Inter-option Synchronization Status
Access RO Range Unsigned 8-bit
Default N/A Update Rate Immediate
Bit Meaning Description
0
Requested Inter-Module
Synchronization Role
This is identical to bit 1 of the Inter-Option Module
Synchronization Control Parameter as described
above.
1
Requested Inter-Module
Synchronization Role
This is identical to bit 0 of the Inter-Option Module
Synchronization Control Parameter as described
above.
2
Inter-Module Synchronization
Role Achieved
This bit indicates that for a module attempting to
become inter-module synchronization Producer it
has achieved that role. In the event of more than
one module on a given drive attempting to become
the synchronization Producer at least one of these
modules will have this bit clear. For a module
attempting to become inter-module
synchronization Consumer it indicates that it has
not requested to become Producer, and that a
Producer has been located in another slot and is
being used as the source of synchronization data.
(If a Producer has been located in another slot but
the rate of the synchronization data is not
compatible with the Consumer then this bit will be
cleared because the Producer - although located -
is not being used as the source of synchronization
data.)
3
Synchronization Producer
Output within Specification
This bit is relevant only for modules which have
been designated as the inter-option module
synchronization Producer and CTSync Slave. This
bit indicates that the signal being provided by the
inter-option module synchronization Producer is
within the specified tolerance of the drive, and that
the drive is now locked to the CTSync Slave’s
frequency. Note that this bit may only be set if bits
2 to 0 of this parameter are 1,0,1, indicating that
the module is Producer (0,1) and that the Producer
role has been achieved (1).
