Detailed Description
2.1 Various interface signals and functions (A2)
DB19
DBX13.6 Load part program
Edge evaluation: no
Signal state 1 or Load active
edge change 0 → 1
Signal state 0 or Loading inactive
edge change 1 → 0
Application Valid for HMI Embedded;
example(s) a file transfer can be initiated using the hard disk.
DB19
DBX13.7 Selection
Edge evaluation: no
Signal state 1 or Selection active
edge change 0 → 1
Signal state 0 or Selection inactive
edge change 1 → 0
Application Valid for HMI Embedded;
example(s) a file transfer can be initiated using the hard disk.
DB19
DBX14.0 - DBX14.6 PLC index
Edge evaluation: no
Description This byte for control of the V24 interface describes the PLC index for the standard control file,
which specifies the axis, channel or TO number. This file is handled from the PLC → HMI
correspondling to the contract which is in DB19.DBB12.
Application Valid for HMI Embedded, with reference to DB19.DBB12
example(s)
Dependent on:
DB19.DBX14.7=0 → Act. FS: PLC index that specifies axis, channel or TO No.
DB19.DBX14.7=1 → Pas.FS: PLC index for the user control file
DB19
DBX14.7 Active or passive file system
Edge evaluation: no
Signal state 1 or Passive file system
edge change 0 → 1
Signal state 0 or Active file system
edge change 1 → 0
Application Valid for HMI Embedded, with reference to DB19.DBB12
