Software Configuration Tags E-3
Configuration Data Tags Table E.1 lists the configuration data tags available on your 1756-SYNCH
module. These tags control the configurations described in Table 3.7 on
page 3-18.
Input Data Tags Table E.2 lists the input data tags available on your 1756-SYNCH module.
Table E.1 Configuration Data Tags
Name
(x = module’s chassis slot location):
Type: Definition:
Local:x:C.ChassisCSTMst BOOL If this bit is set to 1, the module becomes the CST master for its chassis.
Local:x:C.SLCSTMst BOOL If this bit is set to 1, the module becomes the CST master for the entire
SynchLink.
Local:x:C.RemainChassisCSTMst BOOL If this bit is set to 1, the module remains Chassis CST master for its chassis
even if communications with the SynchLink CST master are lost.
Local:x:C.TempChassisCSTMst BOOL If this bit is set to 1, the module acts as Chassis CST master for its chassis
and ignores the SynchLink CST master.
Table E.2 Input Data Tags
Name
(x = module’s chassis slot location):
Type: Definition:
Local.x.I.Fault DINT
Local.x.I.ChassisMultiMaster BOOL 0 = The chassis has no CST master or one CST master
1 = This module is configured to be CST master, but another module is active
as CST master.
Local.x.I.ChassisCSTFault BOOL 0 = Chassis CST value is not faulted.
1 = Chassis CST value is faulted.
Local.x.I.SynchLinkRxFault BOOL 0 = The module’s receive port is functioning properly.
1 = A fault has occurred on the module’s receive port.
Local.x.I.SynchLinkDataFault BOOL 0 = Either no data received from upstream module (see other faulty bits) or
upstream device not in idle state
1 = Upstream device producing data for this module is in the idle state
Local.x.I.SynchLinkFormatFault BOOL 0 = The module’s communications formats are properly configured.
1 = This modules receive port communications format does not match the
upstream module's transmit port communications format
Local.x.I.SynchLinkMultiMaster BOOL 0 = One node is configured as the master of the SynchLink .
1 = Multiple nodes are configured as the master of the SynchLink.
