It supports the M4 master profile (AS-Interface V3.0), handling up to 62 slaves and 496 digital inputs and outputs each. IP20 rating applies. Configuration runs through STEP 7 using the command interface, with access to analog I/O via data record transfer and digital I/O through the process image. AS-i connection uses screw terminals, and the module supports AS-i Power24V. Horizontal mounting allows 0 to 55°C ambient; vertical mounting extends the range to -25 to +70°C. Maximum altitude 2 000m. The module is powered exclusively from the S7-1200 backplane bus; no external supply needed. Maximum 3 communication modules (CM/CP) per CPU. LED indicators for AS-i, PF, CM, CER, and DIAG provide quick status at the panel door.","metaTitle":"Siemens 6AG1243-2AA30-7XB0 SIPLUS AS-Interface Master, S7-12","metaDescription":"Active SIPLUS CM 1243-2 AS-Interface master for S7-1200, conformal coating, -25 to +70°C vertical, 62 slaves, 496 I/O, 250 mA backplane supply, screw terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC Communication Modules"],"specifications":{"Note":"All product versions","title":"6AG1243-2AA30-7XB0","description":"SIPLUS S7-1200 CM 1243-2 based on 3RK7243-2AA30-0XB0 with conformal coating, -25…+70 °C, S7-1200, CM 1243-2 communications module AS-Interface master according to AS-i specification V3.0","Module Format":"S7-1200 design","as AS-Interface":"1","lifecycle_stage":"current","Fastening Method":"snap-on fastening on 35 mm DIN rail","Product Designation":"SIPLUS AS-Interface master","protection class IP":"IP20","Type Of Voltage Supply":"via backplane bus","as status display by LED":"AS-i, PF, CM, CER, DIAG","Type Of Data Transmission":"S7-1200 backplane bus","access to analog I/O data":"via process diagram/peripheral addresses and data record transfer","From Backplane Bus Maximum":"250mA","access to digital I/O data":"via process image/peripheral addresses","Insulation Voltage Rated Value":"500V","number of units per CPU maximum":"3","number of units per CPU maximum note":"Max. 3 communication modules in total (CM /CP)","AS-Interface master profile is supported":"M4 (in acc. with AS-interface specification V 3.0)","If Installed On Horizontal Mounting Rail":"0 ... 55°C","number of inputs for AS-Interface maximum":"496","type of configuration of the AS-Interface":"With STEP 7, command interface","number of outputs for AS-Interface maximum":"496","product function suitable for AS-i Power24V":"Yes","number of AS-i slaves per AS-Interface maximum":"62","type of electrical connection of the AS-Interface":"Screw-type connection","If Installed On Vertical Mounting Rail During Operation":"-25 ... +70°C","Installation Altitude At Height Above Sea Level Maximum":"2 000m"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,421.88","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/bd080ad776484bdbc32f6c6a2699ccca.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1204511&mlfb=6AG1243-2AA30-7XB0"},"ai":{"faq":[{"question":"What is the note field for this module?","answer":"The note reads 'All product versions'."},{"question":"What is the module format?","answer":"It is an S7-1200 design module, fitting that platform's backplane and DIN rail mounting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6AG1243-2AA30-7XB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6AG1243-2AA30-7XB0 when reusing this data.
