everyone,
I’m struggling to get communication working between a StepperOnline A8-1000PN servo drive and a Siemens S7-1200 CPU 1214C via PROFINET and need some guidance.
Setup:
• PLC: Siemens S7-1200 CPU 1214C DC/DC/Rly
• Servo drive: StepperOnline A8-1000PN (1kW, 200-240V)
• Software: TIA Portal
• Telegram: 12 \[Profinet\] configured in drive
• Encoder: 17-bit absolute magnetic, no battery (used as incremental)
• GSDML file installed in TIA Portal
Current issues:
1. MC function blocks (MC\_Power, MC\_Reset, MC\_MoveVelocity, MC\_MoveJog) showing red with instance DB errors inside FB1
2. Unsure if S7-1200 fully supports PROFINET servo control with MC blocks the same way S7-1500 does
3. Not sure if Telegram 3 or Telegram 12 is better for this drive with S7-1200
Goal:
• Run two motors, master sends encoder signal and slave synchronizes for a flying shear/cut application
