Siemens 12586 - Block motion synchronous action: type conflict in variable

Type conversion is not possible for online variables $A. or $V., which are evaluated or written in the interpolation cycle. Only variables of the same type can be linked or assigned to one another. Example 1: WHENEVER $AA_IM[X] > $A_IN[1] DO. An online variable of the REAL type (actual value) cannot be compared with a variable of the BOOL type (digital input) The operation is possible if the following change is made: WHENEVER $AA_IM[X] > $A_INA[1] DO. Example 2: WHENEVER. DO $AC_MARKER[1]=$AA_IM[X]-$AA_MM[X] Improvement: WHENEVER. DO $AC_PARAM[1]=$AA_IM[X]-$AA_MM[X] Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Common Causes

  • Type conversion is not possible for online variables $A.. or $V.., which are evaluated or written in the interpolation cycle.
  • Only variables of the same type can be linked or assigned to one another.
  • Example 1: WHENEVER $AA_IM[X] > $A_IN[1] DO ... An online variable of the REAL type (actual value) cannot be compared with a variable of the BOOL type (digital input) The operation is possible if the following change is made: WHENEVER $AA_IM[X] > $A_INA[1] DO ... Example 2: WHENEVER ... DO $AC_MARKER[1]=$AA_IM[X]-$AA_MM[X] Improvement: WHENEVER ... DO $AC_PARAM[1]=$AA_IM[X]-$AA_MM[X]

Troubleshooting Steps

  1. 1Modify part program: Use variables of the same type.
  2. 2Clear alarm with NC START or RESET key and continue the program
