Powered from the backplane bus, it draws up to 220 mA, adding 3.7 W to the CPU power budget. A maximum of two modules per CPU is allowed. ## Scan Performance and Diagnostics Six front-panel LEDs — PWR, APF, CER, AUP, CM, SF — give immediate read on bus health and communication errors, making commission and fault-finding straightforward without a programming tool. Occupies a standard 71 x 80 x 62 mm envelope with IP20 protection.","metaTitle":"Siemens 6GK7243-2AX01-0XA0 AS-Interface Master, 62 Slaves","metaDescription":"Current-production AS-Interface master for S7-200.
