It connects the controller to a PROFIBUS DP network with up to 8 DP slaves, and supports up to 4 simultaneous connections to other S7 stations. The interface is a 9-pin Sub-D socket (RS485) on the first port; there is no Industrial Ethernet port. DPV0 and DPV1 are both listed as No — meaning this module handles standard PROFIBUS DP communication but not the extended DP-V1 services for acyclic parameter data or alarm handling. Supply is 24 VDC external, with a +/-20 % tolerance band, fed through a 3-pole terminal block. Power dissipation is 2.4 W — negligible for the thermal budget in a crowded S7-1200 rack. ## Panel fit and temperature range Mounts on 35 mm top-hat DIN rail or can be wall-mounted. Dimensions are 75 mm deep, 30 mm wide, 100 mm tall — the single-width S7-1200 footprint leaves room alongside other modules. Operating temperature range: horizontally mounted busbars -25 to +55 °C; vertical installation -25 to +45 °C. Storage and transport -40 to +70 °C. Conforms to EN 60721-3-3 class 3S4 and EN 60721-3-6 class 6S3 for sand, dust, and vibration — the supplied plug covers must stay on unused interfaces. ## Lifecycle and software requirements Requires STEP 7 Basic/Professional V11 (TIA Portal) or higher for configuration. The module handles up to 244 bytes of input and output address range per DP slave, plus 240 bytes of diagnostic data per slave.","metaTitle":"Siemens 6AG1243-5DX30-2XE0 PLC Communication Module","metaDescription":"Siemens 6AG1243-5DX30-2XE0 S7-1200 compact PROFIBUS DP module, 24 VDC supply, 8 connections max, IP20.
