If your BOM specifies 0..20 mA sensors, plan for manual fault checking or a separate IO-Link master upstream. Diagnostics include a diagnostic alarm, limit value alarms (two upper, two lower per channel), channel status LED (green), and a module diagnostics LED (red). No group error LED, no isochronous mode, and no MAINT LED.","metaTitle":"Siemens 6ES7531-7MH00-0AB0 Analog Input, 0-20mA","metaDescription":"Active production.
