pallen Posted December 19, 2005 Report Share Posted December 19, 2005 Season's Greetings LabView peoples, I'm just curious if anyone else has worked with these Robocylinders from IAI. http://www.robocylinder.com/products/actuators/default.asp We've just started using them ourselves, and I'm still in the "figuring things out" stage. They can be controlled both digitally and serially. I've already got digital controls working. But for my particular application I need both digital and serial. Quickly trying the examples in the manual using the Basic Serial LV example resulted in no response from the controller at all. I ran a sniffer to see what the proprietary control program was sending back and forth to the controller and it didn't look much like what printed in the manual. I've still got a lot of reading to do. But I was just curious if anyone had already worked with them. Quote Link to comment
AnalogKid2DigitalMan Posted December 19, 2005 Report Share Posted December 19, 2005 There are a lot of broken links on their site, I could not get to the Serial Communication White Papers. Have you tried Hyperterminal first? Proper serial cabling? Correct termination character used in LV? Quote Link to comment
pallen Posted December 19, 2005 Author Report Share Posted December 19, 2005 I noticed a lot of broken links as well. This link (http://www.intelligentactuator.com/) appears to be for the same company. But has fewer broken links. After a call to their Chicago office, I managed to figure out what I was doing wrong. I wasn't sending the control codes (STX and ETX) correctly. I ended up having to look up how to do this in LabView. At least I'm able to send a simple status request now. But it looks like I've got a whole lot of reading to do before I'll be close to what we want to do with them. Quote Link to comment
denisetucker Posted October 24, 2006 Report Share Posted October 24, 2006 Sounds like you might have found the command list for the robocylinder. Any chance you've still got your hands on it? I too am trying to develop a LV driver for it. Any hints? Thanks, Denise Quote Link to comment

THese cyclinder are really easy to deal with ONCE you figure a few things out , do you have the ROBO Cylinder Serial Communications Protocol document ?? if not i can scan it and send it to you....

Finally found the documment. (Their site is difficult to navigate.) I'm trying: 7) Position Inquiry To poll the current position of a system addressed as #0 that has been homed to the motor end and has a 12mm lead, send the following string: Chr$(02) + 0R40000740008F + Chr$(03) I'm sending this using the Basic Serial Write and Read at 38400,8,N,1, FlowControl=None, and a 1 sec delay before read. I've tried FlowControl=RTS/CTS. I've tried \n and \r\n. Any suggestions? Quote Link to comment

Thanks much, Denise Ok here is everything i have to work with the ROBO's , you will need to change some of the defaults since you have a different lead length. the first 3 things you need to do is INIT, POWER ON, HOME after that you can do whatever you need. these VI's still need some work , but, they got me through what i needed , i actually want to try to re-write them using LabVOOP. if you have any questions feel free to ask. good luck Dan Ok here is everything i have to work with the ROBO's , you will need to change some of the defaults since you have a different lead length. the first 3 things you need to do is INIT, POWER ON, HOME after that you can do whatever you need. these VI's still need some work , but, they got me through what i needed , i actually want to try to re-write them using LabVOOP. if you have any questions feel free to ask.good luck Dan Here are the the protocol manuals that i have in case you or anyone else needs them ....

martinGer Posted June 15, 2007 Report Share Posted June 15, 2007 Hi Dan, Hi Denise, Can you guys do me a favor and convert the ROBO vi's to LV 8.0 or 7.1 please. I'm trying to establish a commuincation to IAI-TT series and all the work you have done already may help lots. Thanx in advance Martin Quote Link to comment
water Posted December 25, 2007 Report Share Posted December 25, 2007 Hi Dan, I use the system as below, 1. PSEL Controller: PSEL-C-2-56PI-NP-20PI-NP-2-0 2. Actuator: RCP2-SS8C-I-56P-5-100-P1-M-B 3. Actuator: RCP22-RA2C-1-20P-1-25-P1-S I tried to use your code, it cannot power on as the attached code, please sugget me. Thank you very much for your help. Quote Link to comment

Thank you very much for your help. well first off make sure he serial port is configured properly... make sure you can connect using their PC interface software , i have only used it with the RCP2 controller , but , usually the problem is a comm problem or the Unit Number is set wrong...

DoubleU Posted February 15, 2009 Report Share Posted February 15, 2009 Hi, currently i work with a RCP2 axis from IAI. To controll it i use the PCON-SE controller. It is possible to communicate with this controller in ascii and rtu over the serial com port. The communication with the IAI Software is works fine. Now i try to write a programm with LabVIEW to communicate with the controller. It is a modbus Port so i tried the Modbus libraries from the offiziell NI.com site. There i also finde the Link to this thread. I tested to communicate with it with the ROBO.vi but it doesen´t work. I currently under time pressure with this projekt. It would be nice if you could help me to get a simple communication to make the first step and move the axis. The offcut go without saying. At least i hope so. Befor i forget to say its an projekt in the apprenticeship. I hope you can help me. regards DoubleU Quote Link to comment
DoubleU Posted February 16, 2009 Report Share Posted February 16, 2009 Here is the Datasheet of the PCON controller. Perhaps I can communicate over the Modbus libraries from the Ni.com site. But how can i send the correct command to the correct address. In the Modbus libraries it is possible to send a Modbus command to the Device but i must be a cluster of more comments and I can´t finde the option to send the command as it is required in the Datasheet. regards DoubleU Quote Link to comment
