Hi All i want to adjust the offset in DA041 analog output module, as the out command word is 0000 but the voltage output are +0.5, i want to make it ZERO. module is in adjustment mode. the fuction used is CLR. my unit no is 2, in cio 2020 bit 00 and 01 Set at 1 turn ON of the offset bit in 2021.00 monitor 2028, but its showing 0000 i tried to adjust value via 2021.03 but in CIO 2028 no change is obserevd. multimtere is connected with the out put and no change at all. even i tried to up and down the value it not changing. please help regards NASIR

Hi team i am still waiting for a reply regards Nasir

Dear Mate after making settings dm36=9999, or dm36=0494 the P_CY flag turn ON and OFF, Try to reduce the Prop Gain to 50, and fixed the sampling time to 0.1s, b but the out put is still ZERO.

Dear Mates, Happy New Year!!! i am new in plc programming, want to learn use of PID command i am using a 4-20mA input and scale it (#30---#7FF that converts to 0--100) make a small step for continous change of the input and getting a perfect output after scaling when i am using the scalled output in PID command, as Input word and setting the parameters as below, getting no output. the error flag is ON ( program is attached) For C #100 For P, C+1 &500 For I, C+2 turn if off &9999 For D, C+3 turn if off &0000 For t, C+4 say &50 which corresponds to a 0.5 sec sampling period Leave C5 &0001 C6 #0404 C7 to onwords not using please help me, whats going wrong here. regards NASIR PID TEST.cxp

Dear Jay and PDL Thanks for your kind support and help regards NASIR

Dear Jay but the manual says that ORDER OF OCCURRENCE: Alarm Messages are displyed in order of occurrence (from oldest recoed or from newest record) The order in which alarm message displyed depeneds on the system memory settings if it is not supported and new alarm came in bottom, so what does the meaning of the line above? regards NASIR

Dear Team i am programming NT-30 ST141 i have set the alarm history to make the log of alarms by taking as ORDER OF OCCURRENCE but the new alarm log is come in the bottom. but i want it on the top and move the old one down. please find the attached manual description for this setting, can you please suggest which system memory setting i have to adjust? regards NASIR

Dear Michael i am totally agree with you that PMCR is more eaisy to use annd work. but here a question rasied, for those PLCs which are not compatible or not support PMCR, so how these PLCS work with RS485 or Modbus communication How CRC16 calculated for these PLCs. so i need your help to communicate the PLC with 3g3jx with out using PMCR. regards NASIR

Dear Jay make a ladder logic for with TXD and RXD commnds. when i turn ON the TXD the port 2 SCB41 turn ON, inveter also behaves that it is communicating with the SCB, and No communicaton alarm on the disply of inveter. i am trying to turn ON the coil to RUN the inveter, but it is not please find the attahced command format descriebed in the 3g3JX manual and also the PLC program. please review it and suggest what should be the exact command format to enable the inveter to come at RUN mode regards NASIR TXD-RXD CQM1.cxp

Dear Jay TXD and RXD converts the data to ASCII and then transmit and recieved. but the 3g3jx communication setting shows that Data bit length= 8 bit Modbus RTU ( ASCII mode not availabe) can we do data tarnfer in that case? regards NASIR

Dear Grey thanks for the manuals. If we see the SCB41 Manual it shows that there is a NO PROTOCOL Setting for TXD and RXD. but when we look at PLC Settings, there is no such setting availabe. as shown in the attahced, This make me confuse. can you please help regards NASIR

Dear Michael i want to communicate it via Rs485 without protocol macro using TXD and RXD command. could it communicate? regards NASIR
