Chapter 11 DeviceNet Remote I/O Module AHRTU-DNET Note: AH10SCM-5A can only be mounted to the main rack. The data mapping length of the digital I/O module connected to AHRTU-DNET-5A is fixed. Those of the analog I/O module and AH10SCM-5A are the data length of the mapped parameters for I/O data exchange and can not be modified. When AHRTU-DNET-5A connects the analog I/O module and AH10SCM-5A, the mapped data that AHRTU-DNET-5A uploads and downloads could be default or optional according to the users’ need. The input and output mapped address length of the selectable parameters of each analog I/O module could not exceed 20 words.
Besides the input and output mapped address length of the selectable parameters could not exceed 20 words, AH10SCM-5A can provide maximum 100 words of input and 100 words of output mapped addresses for serial port data exchange. 11.3.3 Connecting the Cable to the DeviceNet Connector 11-11 Special module Default I/O mapping data length (Unit: Word) DeviceNet→AHRTU-DNET-5A AHRTU-DNET-5A→DeviceNet AH04DA-5A 8 N/A AH08DA-5B 16 N/A AH08DA-5C 16 N/A AH06XA-5A 4 8 AH04PT-5A N/A 8 AH04TC-5A N/A 8 AH08TC-5A N/A 16 AH10SCM-5A 20 38 Please use the special tool to strip off the skin of the communication cable for 30 mm. Note not to damage the shielded wire.
After removing the outer metal shielded net and aluminum foil, you will see 2 power wires (red and black), 2 signal wires (blue and white) and one shielded wire. Strip off the plastic skin of the power wire and signal wire for an appropriate length after removing the outer metal shielded net and aluminum foil of the cable. Insert the stripped communication cable wires to the holes of the communication connector in order as the right figure shows.
