I am using Powerflex 40P drive. I tied the opto output on the VFD terminal (pin 18) to PLC input. I used Drive explorer software to set the VFD parameter A061 (Opto Output selection) = "Motor Running". But when the motor is running, I don't see this output turn ON. Any ideas why? See attached...
Thanks everyone for their inputs. Looks like the VFD was a bad one. I received a new Powerflex 40P this week and it worked right out of the box. Now I am able to use the 1203-USB cable and connect to the VFD and modify the parameters using the Drive Explorer software as well. I did not have to...
Hi eeprom,
The problem is that ther is NO key pad what so ever on this VFD drive. There is only one UP ARROW key available. This up arrow key is to read the BASIC PROGRAM parameters 0-9 READ ONLY. I cannot change any parameter from the VFD interface!!
My laptop is connected to Powerflex 40P via 1203-USB cable. I am trying to use DriveExplorer software to communicate to the VFD. Here is the problem:
According to the user manual for the 1203-USB cable, the RS-485 port on the VFD must be configured for 19.2K baud rate.
But the default value...
On the Tools menu --> Goto Feedback zone.
Select References Tab.
Select (Highlight) the tag in the ladder logic that you are interested.
You will find the list of all the tag locations under the references tab.
I have used Allen-Bradley and Mitsubishi PLC and they have the cross-reference feature on ladder logic software to find all the locations where the tag is used in the program. But on the Proficy 7.0 Machine Edition, I see that this cross-reference feature is missing.
Any suggestions how to...
Thanks Controlsdude. The E-stop logic is in the Smartguard controller. When the RESET push button is pressed, then I trigger the external contactor relay and monitor the contact(NC). Then I trigger the "Safe-off enable" signal to drive the safe-off board. Then I trigger the "Drive enable" signal...
When I use a contactor monitoring circuit, then I pretty much know when the drive (VFD or servo drives) is powered, right? Then why do we have to buy the additional safe-off board (especially to the Powerflex Allen-Bradley drives)? Whats the purpose? Is it to get an additional safety certificate...
Yes U are absolutely right about that. Contrary to what the user manual says, u cannot add the smartguard in the IO tree of the Logix 5000 software. U have 2 add tags in the "Slave I/O" configuration tab in SmartGuard configuration in RSNetworx so that it appears in the "scanlist" of the DNB...
Has anyone setup communications between a GuardLogix PLC and a SmartGuard Controller on a devicenet?
I setup the smartguard for COS with 2 bytes input and 1 byte output data(on the RSNetworx for DeviceNet).
I had to create "Generic Safety Module" on the IO config on the Logix 5000.
But for...
I brought down the foreground and the background scan class. But that is only for scanning the tags right? So my question is the major factor that affects the HMI animation response speed.. is it the bandwidth of the network??
The animation on the RSView32 screen seems to be too slow to react. After pushing the button it takes atleast 2 secons for the animation to take effect. Is there a solution for that?

Has anyone used heater controllers using RedLion CSPID controllers with modbus protocol? It uses Crimson software for creating data blocks and setting up communication parameters between the controllers and the PC. I am looking for any examples based on the Heater applications.
Hello. MY question is regarding profibus DP on siemens plc. this is my first time with siemens. i have done a few projects with AB in the past. This particular project has the distributed safety software besides the step-7 software. The code is pretty much done and has been tested on other tools...
I am trying to see if the 232c unit (used for devicener to serial interface) works. So I have used it as an interface between a AB PLC and a PC (hyperterminal). Now I have checked the baud rate, parity , stop bits of the serial port on the interface through the RS Networx for devicenet. I have...
thanks djs. i figured it out and now all the settings are fine. i have mapped the memory alright and able to see the tx flag on.
but i need help with the Mettler toledo weigh scale wm6002.this is the device attached to the 232c interface unit. i am able to see the SEND LED come on everytime the...
I am using Controllogix plc ,devicenet scanner card to read OMRON drt1-232c unit(devicenet to serial) which has a peripheral device connected to its serial end(in this case it is a weigh scale). i wuould like to know how the memory I/O is mapped on the devicenet memory. i setup using RSNetworx...
