It handles 8-byte inputs in standard mode and 32-byte inputs in performance mode, with matching 32-byte outputs in performance mode — the performance mode doubles the data throughput for applications like Modbus RTU or ASCII protocol exchanges. ## Serial Flexibility — Three Physical Layers, One Order Code The module supports RS-232 with auxiliary signals (RTS, CTS, DTR, DSR, RI, DCD), RS-422, and RS-485 — all selectable via the configuration software, so a single part covers point-to-point, multi-drop, and full-duplex links up to 115.2 kbit/s. Cable length reaches 1,200 m on RS-422/485, and the module handles parity (none, even, odd, always 1, always 0, any) and stop bits (1 or 2) — enough to match legacy device protocols without an external converter. Diagnostics include a green/red DIAG LED, diagnostic alarm, wire-break detection, and I&M data (I&M0 to I&M3) for asset tracking in a TIA Portal environment. ## Integration — Push-In Terminals and TIA Portal Compatibility Connection is via push-in terminals — no screwdriver needed for solid or ferruled stranded wire, which speeds panel wiring on the ET 200SP base unit. Compatible with SIMATIC S7-300, S7-400, S7-1200, and S7-1500 controllers via the ET 200SP backplane, with automatic encoding and firmware update capability. The 15 mm width and 58 mm depth fit the standard ET 200SP footprint — no extra DIN-rail space beyond the base unit slot. Power draw is 0.7 W typical, 35 mA max at 24 VDC — well within the backplane power budget of a standard ET 200SP station.","metaTitle":"Siemens 6ES7137-6AA01-0BA0 PtP Module, RS-232/422/485","metaDescription":"Siemens 6ES7137-6AA01-0BA0 PtP communication module for ET 200SP.
