专家置评
STOPU:
SIMOTION D4x5 is not processing a user program.
1.The technology packages are active.Test and commissioning functions can be executed.The user program is not active.
2.The I/O modules are in a secure state. (this means, for example, that digital outputs are "LOW" and analog outputs are deenergized or at zero current).
