A-B 1746-BLM Blow-molding Module

M1 File 

contains four axis-status structures, four process-variable profiles, 

and a single interpolated profile. Axis-status structures are copies 

of respective axis-control structures, except that status 

information has been inserted by the module. Each 

process-variable profile provides a record of the actual position 

response to a setpoint profile. The interpolated profile is the 

result of either a linear or natural cubic-spline interpolation 

performed between the setpoints specified in the master setpoint profile. 

Unlike the Input File, which is automatically updated, the 

module must be explicitly instructed to upload axis-status 

structures, process variable profiles, and the interpolated profile 

to shared memory (done by setting bits in the Output File). 

Entries in this file are then read by move or copy instructions in ladder program.
