It provides anRS485 serial link (2 or 3 wires) with JBUS/MODBUS protocol for the use of DIRIS A40/A41from a PC pointsFor a standard configuration, an RS 485 link is used toconnect up to 31 DIRISor COUNTIS Ciwith a PC ora PLC over a distance of 1200 metres, usingJBUS/MODBUS 1 N 2 N n R = 120 1200 MR = 120 ProgrammablecontrollersOther systemsN 1 R = 120 ProgrammablecontrollersOther systemsrepetorRS485 0+- -+0 N n R = 120 1200 M1200 MDIRIS 109 E GBDIRIS 110 E GBRecommendations:You should use a shielded twisted pair (LIYCY type).

3 Ina disturbed environment or large network (in terms oflength) we recommend the use of a shielded twistedpair (type LIYCY-CY). A repeater (1 channel) or an arrestor (4 channels)should be used if you intend to exceed the distance(1200 m) and/or maximum number (31) of contact us for more :A 120 ohm resistance (found on the additional module)must be fixed at both ends of the solutions are available (modem, optical fibre, etc.).Please contact personnel and product safety please read thecontents of these operating instructions carefullybefore the following points as soon as you receivethe DIRIS A40/A41package: the packing is in good condition, the product has not been damaged during transit, the product reference number conforms to yourorder, the package contains the product and the INFORMATION5 SOCOMEC - R f.

5 : CDR 27 038_gbGBDIRIS A40/A41- RS485 - JBUS/MODBUS COMMUNICATIONThe JBUS/MODBUS used by the DIRIS A40/A41involves a dialogue using a master-slave hierarchicalstructure. There are two possible dialogues: the master communicates with a slave (DIRIS) andwaits for its reply the master communicates with all the slaves (DIRIS)without waiting for their mode of communication is the RTU (RemoteTerminal Unit) using hexadecimal characters of at least8 to the JBUS/MODBUS protocol, transmissiontime must be less than 3 silences, the emission timeof 3 characters so that the message is processed bythe correctly use information, the following functions areimportant:3: to read n words (maximum 128).6: to write one : to diagnose exchanges between the master andthe slave via meters 1, 3, 4, 5 and : to write n words (maximum 128).NB:When selecting slave address 0, a message is sent toall the instruments present on the network (only forfunctions 6 and 16).
