'0110.0100' nibble separated with dots (.) 1.7 Scope This manual describes the Special Module 750-643 MP-Bus Master Module of the modular WAGO-I/O-SYSTEM 750. Handling, assembly and start-up are described in the manual of the Fieldbus Coupler. Therefore this documentation is valid only in the connection with the appropriate manual. -
Page 10: O Modules
The I/O module 750-643 module acts as a MP-Bus Master that is integrated into a fieldbus communications controller for local control. The fieldbus network controller communicates from a network, such as Ethernet or LonWords to bridge data to the MP-Bus Master module. - Page 11 When configuring the system, it must be ensured that this total current is not exceeded. If this should be the case, then an additional supply module must be used. The module 750-643 can be used with all WAGO-I/O-SYSTEM 750 controllers, except of the MODBUS programmable controllers 750-812/-814/-815/-816.

Page 15: Process Data
2.1.1.7 Process data The bus module 750-643 makes an 8-byte process image available to the fieldbus controller via 1 logical channel. The data to be sent and received are stored in 6 output bytes (D0 ...D5) and 6 input bytes (D0 ...D5). Two control bytes (C0, C1) and two status bytes (S0, S1) are used to control the data flow. - Page 16 The IEC application can be implemented in the connected programmable fieldbus controller (PFC) of the fieldbus node with the WAGO-I/O-PRO or WAGO-CAA programming tool.

Page 17: Data Transfer
The byte length of pure MP/PP telegrams varies between min. 4 bytes and max. 10 bytes. The typical length is 7 bytes. The module bus communication of all WAGO-I/O-SYSTEM 750 fieldbus controllers provides a maximum of 8 bytes, including control and status bytes, in each module bus telegram. MP- Bus messages must therefore be split. -
