The width of the end module is 12 mm. Whenassembled, the I/O modules have a maximum length of 768 mm.Examples:• 64 I/O modules with a 12 mm width can be connected to a fieldbuscoupler/controller.• 32 I/O modules with a 24 mm width can be connected to a fieldbuscoupler/controller.Exception:The number of connected I/O modules also depends on the type of fieldbuscoupler/controller is used. For example, the maximum number of stackable I/Omodules on one PROFIBUS DP/V1 fieldbus coupler/controller is 63 with nopassive I/O modules and end module.Observe maximum total length of a fieldbus node!The maximum total length of a fieldbus node without fieldbus coupler/controllermay not exceed 780 mm.Also note the limitations of individual fieldbus couplers/controllers.Pos : 26.3 /Serie 750 (WAGO-I/O-SYST EM)/M ontieren/D emontieren/M ontage auf Tr agschi ene ( XTR) @ 24\mod_1444997402760_21.doc x @ 193805 @ 233 @ 1
