Alarm 12583

Siemens 12583 - Block variable no system variable

In motion synchronous actions, only special system variables are allowed on the left side of the compare operation for the assigned variable as input and result variable of SYNFCT and as input variable for PUTFTOCF. Real-time synchronous access is allowed here. The programmed variable is not a system variable. Example: DEF REAL OTTO, BERTA[2] DO SYNFCT(2,OTTO, $MN_.); Local variables or machine data are not allowed as parameter for SYNFCT Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Siemens 12583 - Block variable no system variable

Block variable no system variable

In motion synchronous actions, only special system variables are allowed on the left side of the compare operation for the assigned variable as input and result variable of SYNFCT and as input variable for PUTFTOCF. Real-time synchronous access is allowed here. The programmed variable is not a system variable. Example: DEF REAL OTTO, BERTA[2] DO SYNFCT(2,OTTO, $MN_.); Local variables or machine data are not allowed as parameter for SYNFCT 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

  • In motion synchronous actions, only special system variables are allowed on the left side of the compare operation for the assigned variable as input and result variable of SYNFCT and as input variable for PUTFTOCF.
  • Real-time synchronous access is allowed here.
  • The programmed variable is not a system variable.

Troubleshooting Steps

  1. 1Modify part program.
  2. 2Local variables or machine data are not allowed as parameters for SYNFCT.
  3. 3Clear alarm with NC START or RESET key and continue the program
