Can any one tell me what software and cable i need to upload a program from a Melsec F-40M. where can i find more information about the melsec F-40M

Thanks guys, my problemis solved. i deleted all the BTR and BTW instructions and iserted then again in the ladder and they all work fine!!!! Thanks for the help i really appreciate it!!

I tried to read data from an Analog input module, But the ER bit in the BTR instruction is on. When i read the fault code, it is -3. The explantion of this fault code is The size of the block transfer plus the size of the index in the block transfer data table was greater than the size of the block transfer data table file. What can i do to correct this Fault???? I am unsing and PLC5 and the analog input module is 1771-IFE Thanks

When i tried to attach the code, i get the message that i am not allow to attach file of that extension, how can i post the code?

Hi everyone, Here is a little bit more discription; I am using a total of 4 analog input modules, two on rack two and the other two on rack four. these analog module are located on two different chassis (1771 - ASB series B adpter). I also have 4 analog output modules, two on rack 2 and the other two on rack 4. The analog output module on rack 2 are working perfectly. The other give me also the same error (DLEN = -3) which has the same discription as mention as in my prevoius vote. None of the 4 analog iput module is funtioning properly. The error code is again (DLEN = -3). The block tranfer code have be entered automatcally, so i think the length of the data tranfer is correct?. i have also verified that the are in range of what the document that Mickey post. attached is part of the block transfer instructions.

Dou you mean that if the next BTR Data file for another module starts at N30:33 that i will get this error?

Hi, everyone. I have recently encontered the same problem with two different Micrologix 1000 PLC. when power is connected to the PLC the fault led is lit and communication is not possible with the PLC. sometimes when power is switch off and on again, the error is gone and communication is possible with the PL but most of the time the fault led is on. have any encountered this problem and what are the remedies. One PLC can have and hardware fault but two doesn't seem likely. Best Regards

To share with you all, It seems like the Micrologix PLC's that i am using are affected by a know technical issue which has been confirmed by Rockwell Attomation. This has been discribed i a word document Rockwell Automation Answer ID 34047 The PLC's will be replaced at no charge. Thanks to You all. Micrologix_1000_release_note.doc

Hi guys, is there a forum forum for Citect scada

the problem could be that the version of the program in the E300 do not correspont to the version of E-designer. try to upgrade the version of the operating system of E300. at startup the E300 should display it version. the version of the operting terminal can be upgrade using the HMI tools which is supply with e-designer

Hi guys, after uninstalling citect and deleting the citect directory and reinstalling citect, i finally got the test program to work, i agree with you PDL about the topic that the FX2n support multidropping thanks for helping me out

i have try to connect with citect to a multidrop fx serie network, but nothing seems to be working. on the side of the PC with scada i have tried differnt styles of wiring method, 422, 485 and still nothing work. i have tried a one on one communication with one of tthe PLC using the programming port and SC09 cable. still citect scada is not able to read one address of the PLC, i get the error cannot talk. should citect scada not be able to read from the PLC directly if connected to the pLC programming port with the used of the original SC09 cable

HE Jimbo, i know my comport, because i use the same com port to communicate with the PLC via GX developer. the comport is selected correctly i am using citect scada version 6 i have attached the scada test project as zip file. you will have to unzip it first the test project have to turn a light green on the graphic page when the PLC is run mode testproject1.rar

i have set up a RS485 network between 7 FX serie's PLC using the FX485 ADP. i have used the two pair wiring method to hookup the PLC to each other These PLC and connected to a citect Scada system on a PC. What should the communication format be in the D8120 to properly commmunicate with Citect Scada

It's also that simple, just go to the vieuw dropdown menu than you can get the job done. I would advise you to get hold on the software manual of GX Developer

It helps a lot to know that someone as a working apllication. i didn,t want lay down the fysical network to find out that i had to look for a other sulotion . many thanks

I have been working on a multidrop network between 7 FX serie PLC. the Purpose of the network is to collect data from and monitor the PLC using Citect Scada. i know that the FX serie PLC support multidrop networking. (Mitsubishi sell the these modules ).. in the manual of citect is written the the melsec - F protocol which the FX -serie uses doesn't support multidrop networking. Will i be able to communicate with the 7 PLC using Citect scada using only one Com port on the PC

there are a lot of software that convertt RS232 to IP, does anyone no if there is a software to directly Convert RS485 to IP

Hi JimBo, you are probably using the FX-485 -ADP module or the FX-485-BD. How many serial ports are you using to communicate with the 11 PLC's?

yes Citect could be use instead of the interface, but that is my last option . they are so use to the interface . and i think the would find it a little bit difficult too.

Hi Guys, i have been working to setup a serial RS 485 hostlink network between 7 CPM1A Plc's. i.m planning to use RS 485/422 module. i have already purchase these module The problem is that there are already HMI terminals connected to the port where i suppose to plug in these module on the left side of the plc,s. is their a way to overcome this without removing the HMI terminals.

the purpose of the network is to collect data and to monitoring the PLC using Citect Scada. i figure out that serial comunication was the best option for me. less cable and less expensive. What other option are you talking about. definetly the terminal that describe in my ealier post is connected to the CPM1A. How is connected ??????? if you said it cannot be connected directly

waynes, the PC that i am planning has an RS485/422 card from advantech. the card has only dual ports. i planning to use 0ne to port to communicated with 7 PLC's of omron that are in a hostlink network. this is not the problem, Citect clearly stated in the user guide that is possible. the other port i will use to communicate with the 7 FX PLC that are in an multidrop network. Will i be able to communicate with the 7 PLC using only one port and different station adresses for the PLC. Why does citect said the FX2n protocol is a point to point sulotion and that it does not support multidrop network.

The HMI Terminal that i am using is NT2S-SF12-1B-EV2 i don.t have the manual of this terminal . i see it has 2 port on the back for communication. Where can i find the manual of this HMI. i have read that the software for this terminal is free . where can i find a free copy of this software many thanks

It would be very nice for you to post your solution so we could learn from it too.
