Restriction on Ladder Programming
Due to the structure of WindLDR, the following ladder diagram cannot be programmed — a closed circuit block is formed by
vertical lines, except for right and left power rails, and the closed circuit block contains one or more prohibited instructions shown
in the table below.
Modifying Prohibited Ladder Programs
Intended operation can be performed by modifying the prohibited ladder program as shown in the examples below:
Prohibited

Relay 2

Prohibited Instructions
OUT, OUTN, SET, RST, TML, TIM, TMH, TMS, TMLO, TIMO, TMHO, TMSO, CNT, CDP, CUD, CNTD, CDPD,
CUDD, SFR, SFRN, SOTU, SOTD
Error Detection
When converting the ladder program, an error message is shown, such as “TIM follows an invalid device.”
Conversion fails to create mnemonics and the program is not downloaded to the CPU module.
