dear sir's,
i have OMRON CJ1M CPU with SCU41-V1 CARD for RS-422/485 communication with omron inverter of model V7 via PMCR(260) Instruction. now i want to replace the V7 inverter with V1000. i have made all the port settings and parameter settings for V1000. but i am not much familiar with cx-protocall. i wnat to edit the send and receive sequence for V1000. i have the sequece as mentioned below for V7 inverter. please can some one help me on this regard.
send message for v7 inverter was written as mentioned below.
send msg:
SD(0)_1 <a>+[100118000102]+(R(2),2)+<c>
SD(1)_1 <a>+[0300230001]+<C>

RECEIVE MSG:
RV(17)_1 <A>[0302]+(W((1),2)+<C>

i could not understand the data [100118000102] which was not clearly mentioned in any of the manual.

thanks and best regards,

cx-protocall

dear sir,
thank you so much for your prompt assistance. here we are using modbus communication. in the PLC program we are using {PMCR(260) instruction with control word 1 as #110(position 0 is used for scu41-v1 card), with control word 2 as (&212, &239, &240) sequence no (1, 14, 15) in the attached photo (1.modbus sequence),& first send word with data of frequency reference1,2,3,4 & acceleration deceleration 1,2,3,4}. the above said program was done for V7 inverter in that i have replaced part of V7 inverter with V1000 which falls under sequence 1(&212). i would like modify this sequence to communicate with v1000 inverter which involves send and receive of 2 bytes of frequency reference. i have attached the photos of cx-protocall which was programmed for V7 inverter. i want to add new sequence, send&receive msg for V1000 inverter. so please help me how to write for the v1000 inverter. the data to be transfered for v1000 is same as of v7. but i confused with register addressing. so please help me to modify as required. thanks in advance
