Countermeasures for PROFIBUS cable noise
When the PROFIBUS-DP unit is being used, expose the cable by removing a part of the cable sheath and make sure to use
the shield clamp for the exogenous noise countermeasure.
When you cannot use the shield clamp, make sure to install a ferrite core as a substitute to PROFIBUS cable (near the
expansion unit). (Recommended model name: ZCAT2032-0930(-BK))
