5. Programming the M91-t4-r6-zk1
Unlike modern PLCs using IEC 61131-3, the M91 series typically uses U90 Ladder Logic (a free, legacy software). The manual’s programming section covers: M91-t4-r6-zk1 Manual
- Connecting the PC: Requires a programming cable (RS232 to RJ11). The "zk1" suffix may include a USB-to-RS232 adapter.
