Please e-mail into support@unitronics.com for more information on this topic. As far as I am aware, this type of input for a C function is only to configure a data table. But I do not believe it will allow you to read/write from a specific data table.

Hello, I don't believe you can address the data table directly in the C function. You would have to perform a 'read row from DTI' to put the row information into a tag. Then pass this tag (which will be a struct) into your C function. It is important to note that when passing the struct into a subroutine, the struct will update with each scan since it is a passed in by reference. You will not have to pass the struct back out - it will be updated as it moves through the subroutine. Hope this helps.

Hello, The relay outputs have about 100,000 cycle lifespan - they are not recommended to be used as pulse outputs. I would recommend switching to a unit that has high-speed outputs. I would suggest one of the following part numbers if you wish to continue with the V130: - V130-TR20 - V130-TR34 - V130-TR6 - V130-TRA22 The TRA22 will most closely relate to the model you have now, it just has 4 relay outputs and 4 high-speed outputs compared to 8 relay outputs that you have now. Hope this helps.

Hello, What kind of driver are you using? What type of inputs does this driver accept? Does it accept communication commands?

Hello, If you put the controller into "STOP MODE", you should be able to program a new application into the unit. -Detach power from the PLC -Press and hold your finger on the screen -Apply power while your finger is still on the screen -Once the unit is powered on, tap once on the screen -After the 10 second time-out, it should enter STOP MODE -Establish communications with VisiLogic (remember, default baud is 115200) -Once comms are established, program unit with new application Please let me know if this helps.

Hello Rich, Since it is a one-shot output from the timer (only on for one scan) you may not see this logic perfom while online with the PLC - it may be happening much too fast for the communciations to catch this logic. What kind of output are you triggering? You may not be seeing anything come from the output since you are only triggering it for one scan - it may need to be on for longer to see an output. What is this output triggering?

Hello Rich, Are you sure the subroutine is running? Is it against teh main rail in the main routine, or are there conditions for the subroutine to run? Can you place an incremeting function block at teh end of net 1 and 2 to see if they are being evaluated? The incrementers should increment (net 1 with scan time, net 2 with timer value) if this subroutine is being called.

Hello Justin, The screen brightnees feature can be changeable through the project level actions. You can link an integer for the screen brightness level, then trigger the bit associated to the action to load the screen brightness level. The supported range is 10-100 for brightness. Hope this helps.

Hello Arie, SDW 24 is a bit map for the UniCAN message buffer. Since you can overwrite the SDW, there is no error currently. It may have happened once and the error message remained in the register. For more information on this exact error message, please contact support@unitronics.com.

Hello Kenedy, Which physical input are you using on the I/O module? Which software input are you minitoring?

Hello, How are you trying to import/export the recipe files? Via FTP?

Also, I forgot to mention, PTO is unavailable with teh snap-in modules. However, we have created an example project that comes with VisiLogic on how to create the ladder for PTO. (Help\Examples...\Version 900\Project Examples\HSC_HSO\V570_Stepper_Motor_PTO.vlp) The EXF-RC15 will only allow 3 PTO channels if you are performing pulse only. If you do not need PTO, you can use PWM instead of PTO to give only pulses out of the high-speed transistor outputs. In this case, will you be able to use the configuration above that you have described. Otherwise, you will need more modules that support PTO. Hope this helps.

Hello, You will need a stepper motor driver that accepts a pulse input as well to integrate the stepper motors.

Hello, When you receive the string, do you convert 1 character to 1 element? Is so, you can compare the first MI of teh buffer vector to the HEX or Decimal equivalent of an "A" (hex = 0x41, dec = 65). Is the compare is true, trigger a bit, and on the positive transition of that bit, store the string into a separate vector. You will have to create the second vector to be the length of the maximum amount of string space you will need. Please let me know if this helps.

Hello, So you know what kind of stepper motors you will be using/ how you will want to communciate to them? For six different motors, you may want to use a driver with some type of communciations (serial/ethernet/CANbus), one that has a common protocol with our products (Modbus/CANOpen/etc.). As for the DO - are you going to need transistor or relay outputs? Would you like them on the back of the unit, or DIN rail mounted in your cabinet?
