I/O failure during the cycle or a set cold restart because of IP/WF modules
(MD 6049, bit 1 = 1) causes PLC to stay in the stop state after the first RE-
SET. A warm restart gives the described error; the cold restart set in the ma-
chine data prevents a warm restart from being executed and message 5FH
appears (warm restart not allowed). After repeating RESET, the cold restart
set in the MD is executed together with a redefinition of the I/Os.
If one of the modules fails on Power off, the PLC executes a cold restart and
goes into cyclic operation; the failed module is ignored.
5F: Error number illegal warm restart
00: No entry in ISTACK or power supply failure not only reason for
interruption or PLC machine data 6049 bit 1 (cold restart bit) set and
warm restart initiated by programmer or PLC mode selector switch.
3C: Changed address location of I/O byte, otherwise I/O type identifier:
01: Centralized I/Os, TPx, LPx
03: 16-bit link
04: DMP
0I or 0Q identifier input/output
Byte number (BCD format)
6C: Error when booting the user program
0001: Memory dump (file on MMC hard disk) does not exist or is empty
0002: Illegal user program file
000B: ICODE error
000C: ADS error (e.g. no communication with MMC)
6D: Error while saving the user program
0001: Scare not possible (reason see F0002)
000A: System error
000B: ICODE error
000C: ADS error (e.g. no communication with MMC)
When F0001 = 0001:
0001: User program memory empty
0002: Boot not completely finished or data loss
