Diagnostic visibility comes from four front-face LEDs covering transmission activity, reception activity (RX), module status, and error, which is the minimum set a controls engineer needs to confirm link state and traffic direction during commissioning or a fault call-out. A built-in web server and a user web page size of 2 MB let the controller serve its own configuration pages directly over HTTP, removing the need for a separate HMI panel for parameter access on machines where only status and setup are required. ## Where it physically lives and what it tolerates Operating temperature spans -20 to 65 °C with storage to -25 to 70 °C and 5 to 95 % non-condensing humidity, and the unit holds its EMC profile against the EN/IEC 61000-6-1 and EN/IEC 60730-1 immunity sets plus the IEC 61800-3 category C1 conducted emissions envelope, which qualifies it for installation next to a drive on the same panel. Mechanical resilience is rated at 15 gn shock for 11 ms and the IEC-standard 1.5 mm / 1 mm / 2 gn vibration sweep from 3 to 150 Hz, with operation specified up to 2000 m altitude — adequate for an enclosed control cabinet on a typical machine or a top-floor equipment room. ## Compliance posture and approval footprint Pollution degree 2 is consistent with an office- or light-industrial cabinet interior — the module should not be specified for an environment where conductive dust or condensation is expected at the card edge. ## Sourcing posture for an obsolete slot card Because the part is recorded as obsolete with no official successor on the same data line, any replacement is a board-level or system-level re-design rather than a like-for-like swap — a buyer specifying this code is patching an existing M168 install where a form-fit-function drop-in is still required.","metaTitle":"TM168MODW Schneider Electric Modbus TCP module, M168","metaDescription":"Schneider Electric TM168MODW Modbus TCP/IP communication module for the Modicon M168 logic controller, obsolete, sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["HMI Operator Interfaces"],"specifications":{"title":"TM168MODW","Marking":"CE","Category":"US1PC1222535","description":"Modbus TCP communication module for M168 base controller w BMS connectivity slot","Web services":"Web server","lifecycle_stage":"eol_hot","Local signalling":"1 LED for transmission activity 1 LED for reception activity (RX) 1 LED for module status 1 LED for error","Pollution degree":"2","Range of Product":"Modicon M168 logic controller","Shock resistance":"15 gn 11 ms","Storage altitude":"0...10000 ft (0...3048 m)","Relative Humidity":"5...95 % without condensation","Transmission rate":"10/100 Mbit/s","Memory description":"User web page size 2 MB","Operating altitude":"0...6561.68 ft (0...2000 m)","Physical interface":"RJ45 - 10BASE-T RJ45 - 100BASE-TX","Vibration resistance":"1.5 mm 3...13 Hz) 1 mm 13...23 Hz) 2 gn 23...150 Hz)","Communication service":"SNMP BOOTP, Modbus TCP/IP FTP Configure IP parameters Read device identification (43/14) Read holding registers (03) Read input registers (04) Write single register (06) Write multiple registers (16) Read/write multiple registers (23)","Nbr. of units in pkg.":"1","IP Degree of Protection":"IP20","Product or Component Type":"Communication module","Integrated connection type":"Ethernet TCP/IP RJ45 - 2 twisted pairs - class D","Communication Port Protocol":"Modbus TCP/IP","Electromagnetic compatibility":"EMC immunity conforming to EN/IEC 61000-6-1 EMC immunity level 2 conforming to EN/IEC 60730-1 Electrostatic discharge level 3B conforming to IEC 61000-4-2 Radiated RF fields level 3A conforming to IEC 61000-4-3 Electrical fast transient/burst immunity test level 4B conforming to IEC 61000-4-4 Surge immunity test level 3 conforming to IEC 61000-4-5 Conducted RF disturbances level 3A conforming to IEC 61000-4-6 Conducted EMC level 2 conforming to EN/IEC 60730-1 Conducted EMC conforming to EN/IEC 61000-6-3 EMC immunity conforming to IEC 61800-3 Conducted EMC conforming to IEC 61800-3 category C1","Ambient Air Temperature for Storage":"-13...158 °F (-25...70 °C)","Ambient Air Temperature for Operation":"-4...149 °F (-20...65 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c930bdd6562a2bfdc74a548fa8c2108d.pdf","sourceUrl":"https://www.se.com/ca/en/product/TM168MODW/modbus-tcp-communication-module-for-m168-base-controller-w-bms-connectivity-slot/"},"ai":{"faq":[{"question":"What compliance documentation does Schneider Electric list for the TM168MODW?","answer":"The recorded marking is CE, with EMC immunity to EN/IEC 61000-6-1 and conducted emissions against EN/IEC 61000-6-3 plus the IEC 61800-3 category C1 envelope; no UL, CSA, or UKCA entries appear in the data for this order code, so North American machinery acceptance of CE-only compliance needs panel-certifier sign-off."},{"question":"What is the closest pin-compatible alternative to the TM168MODW in the Modicon M168 family?","answer":"The Modicon M168 line is the host platform, but a replacement at this slot is a system-level redesign rather than a like-for-like swap, so specify against the existing BOM line rather than expecting a drop-in cross."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/TM168MODW","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/TM168MODW when reusing this data.
