Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the communication. So we want those PLC's to be connected over wifi. Thanks in Advance

Modbus address register exchange between Melsec-Q series PLC and ME96SSHA-MB Power meter
RV3.0 posted a topic in Mitsubishi
Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU) for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan. However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative.- 2 replies

Freewheeling stop in Altivar71
engMoH posted a topic in Modicon / Telemecanique / Schneider Electric
i am using a VSD Altivar71 and controlling it through serial MODBUS communication, the probllem is sometimes after stoping the motor the drives gives the "nst" fault which means according to the programming catalouge "freewheel stop" it doesn't do that all the time but it happens a lot and after uploading the code again to plc the problem is gone for a while before it happens again. i am sure that the fault is happening because if communication because when i controll the drive from hmi it never gives that fault, i checked the setting and tried different cables but it still gives "nst" and motor never moves, i found that in catalouge but i am not sure how to address the problem.-

Mitsubishi GOT27* Writing to Allen Bradley local tags (program tag)
Tuang posted a topic in Mitsubishi
Hi everyone, I just want to layout the structure of the question. I have a GOT2000 (GT27* series) that I have hooked up and communicating with an Allen-Bradley PLC. I have established connection and can pull out certain tags values from the PLC program in RSLogix 5000. While I can read the tag values, I cannot modify them (in certain conditions). So let say that I have a User-Defined Structure named "Smoke_Detector" and here are it's available members: Smoke_Detector: - ALARM (BOOL) - ON_TIME (DINT) * DINT in Allen-Bradley but Signed Binary 32 - Battery_Life (REAL) My question is that while I can read and display the tag and its members through the following: - LAMP for Smoke_Detector.ALARM - Numerical Display for both Smoke_Detector.ON_TIME and Smoke_Detector.Battery_Life But when I tried to modify the values via a Bit Switch or Numerical Input, it does not operate on them. However, if these tags are members are just standalone tags, meaning that they are not within a UDT in RSLogix 5000, then I can operate/ modify them just fine. Here are the things that I have tried: * Making sure that the permission are set to Read/ Write in RSLogix 5000 * Making sure that the tag definition in GT Designer 3 follows the structure where @[channel]:[Network #]:[Station #]::[Tag instance and member (e.g Smoke_detector is the instance and Alarm is member] Any possible insight and input are appreciate!-

Hi all ! I need a help about connection between mitsubishi GOT Simple series (gs2110) to kawasaki robot via crossed ethernet cable on tcp/ip protocol. I actually have a fx3g for main unit of my project, and also i have a kawasaki robot for slave unit. My purpose is basically to control both with HMI. I used RS422 between plc and got gs2112 and I want to use a crossed ethernet cable between robot and got but i did not communicate with ethernet even between pc and got. There is a manuel which I found on internet about GOT2000 Connection Manual (Microcomputers, MODBUS/Fieldbus Products, Peripherals) I think i need to work on microcomputer connection (ethernet) subject, what do you think about that ? I need all advices and ideas which come from you.

Hello All, What are the methods to get the monitoring data from A series PLC? I know its not supported any more, interface modules are not available..., So the basically, If I want to write customer software (may be embedded) what is the protocol I need to follow? I am connected to CPU unit by the way, there is no other modules except few digital and analog interfaces on PLC. Thank you in advance for your direction, direction in any way would help!

Hi guys, I have been trying to sync up my RSLogix 5000 tag to GT Designer 3 (GTD3) objects but I noticed that GTD3 only recognize certain native data types from Allen Bradley Logix5572 Controller (Model 1756-L72). In the documentation that I found, it show that certain AB Native Tags are transferable to GTD3 Data Type (See the attached file "AB Tags to GTD3 Tags" ) One of the User-Defined Data Type from the RSLogix 5000 that I am trying to sync to Text Display Object in GTD3 is called "UDT_MY_CLTR_INFO" here is it's hierarchy of inheritance from RSLogix 5000 Name Force Mask Data Type MY_CLTR_INFO (...) UDT_MY_CLTR_INFO MY_CLTR_INFO.NAME STRING MY_CLTR_INFO.NAME.LENGTH DINT MY_CLTR_INFO.NAME.DATA SINT[82] In my exported tag which is a CSV file, it doesn't list the sub-classes MY_CLTR_INFO.NAME, MY_CLTR_INFO.NAME.LENGTH, and MY_CLTR_INFO.NAME.DATA, it would only list MY_CLTR_INFO. How do I link up my "Text Display" Object in GTD3 with the tag "MY_CLTR_INFO.NAME" whose Data Type is STRING and GTD3 does not have a STRING Data Type? I appreciate anyone that took their time to read my problem and any attempt to help me out. Thank you.

Hello, I'm trying to make communication between a 315-2 PN/DP and MSA Gasgard XL. I want to read out 40010, and 40020 from GasGard, it works sometimes, but most of time the connection does'nt build up. The parameters i using are: Start address: 9 Lenght: 10 Recv_Time: 5s Conn_Time: 5S I did playing with Recv and Conn Time and it effected the rate of succesful connections, but it still drops too often. Also i tried to read only 9 and 19, but then it didn't read 19. Anyone knows how could i optimize the connection? Thanks

I'm looking at project with an OMRON NJ-101. I was planning on using Modbus TCP/IP from the PLC to talk to a MOXA gateway (MB3170) which would then talk to about 7 different slaves over RS-485. Looking at detail at the blocks that are supplied by OMRON (MTCP_NJ V1.3, available from https://www.myomron.com/index.php?action=kb&article=1245), I noticed that it doesn't send the slave ID, which will mean that it won't be able to talk to different slave ids through the one IP Address. I had a look through the actual code and it sends "FF" in place of the slave id. In particular I was looking at the "MTCP_Client_Fn03" block. Is there another way to get the NJ101 to talk the full MODBUS TCP/IP protocol? Is it possible to edit the blocks provided by OMRON? It seems to me that they are locked down. If I could edit it I could just add the functionality Thanks for your help in advance.

Hello, For my assignment, I need to control lights from 2 seperate locations. I have two FX3GE-24M plc's connected through a LAN network. The idea is that when input X004 gets high, relays Y000 to Y004 gets disabled. I'm trying to use the Fixed Buffer communication protocol. Master IP address: 192.168.1.80 Slave IP address: 192.168.1.81 I'm using GX Works2 together with the FX configurator I'm lost in all the different datasheets... Could someone point me to the direction on what settings i need to change using fx configurator and a basic program of communication? Thanks in advance, Dennis
