The cable you have has no access to the required pins, modifying it in any way may well end up with a destroyed connector.

You have the wrong cable. You need a 1763-NC01 to connect via MODBUS/RS485

I hadn't heard of that one. Just to clarify, the flash card mentioned here is inside the HMI, or putting it in other words, you would get the *gfx files straight from the terminal's solid state hard disk. I have never tried this, because no one would let us fiddle with the terminal's hardware...

The older *.MER files were not modifiable, and you'd have to have the *.APA backup files in order to make changes to the terminal. Only in the latest releases (I believe from FT V6.00 and higher) the *.MER can be edited and modified. I was told this by an AB development engineer during a...

Any motor requires both overload and magnetic protection, because the first is related to the thermal state of the motor at any given moment while in operation. If the motor overloads, it will overheat and should be shut off after a certain period of time vs. overload, usually this being 150%...

To connect your flow transmitter to the 1400, you should add the I/O required to do the job (analog, pulse, etc.) if the PLC doesn't already have it. We have successfully implemented a very similar application, totalizing flow transmitter's pulses, using a 1400 PLC. The 1400 Ethernet port is not...

>The better way is to contact local Yaskawa representative. This is the BEST that can be done. Servomotors are only serviceable by the manufacturer's shop, but it's usually cheaper to get a new one. Do not expect to disassemble one of these and get it to work. In other words, servomotors are...

A good starting point would be some of the various existing rules and regulations for electrical installations. For panels, we use the JIC standards for manufacturing equipment, essentially, the "american standards", probably outdated, but very useful. There are some rules of thumb obtained from...

I do not think there's such a device anywhere. You must use something else and implement it. I guess you are in China. There are PLCs that can easily perform the functions you want and more. I know one chinese brand that has the modules you need to make this work. Please e-mail me to...

The only specification that you can find on those modules would be the maximum load they can safely handle; the load draws power from the outputs per its own specifications. If the current drawn excedes that maximum, then a booster relay is mandatory. In case of the analog autputs module, you'll...

There are several things to consider here, mainly the type of encoder output (open collector, differential, totem-pole), then there's the voltages the circuit runs on. It may be possible to do it as you ask, but you'd be better off using a splitter module, or at least use an optocoupler device...

Probably the file you are downloading is configured for a different model terminal. Check this in the project tree under System setup and check if the models and revision numbers are identical. You may have to tweak the terminal select list to pick out the correct one. On the other hand, it may...

You are probably not using the right OL relay. Unbalanced load protection has been built in IEC type overload relays for some 40 years, unless you are using an antique for protection (World war 2 equipment). You should replace it with something newer. If P&B stands for Potter & Brumfield, you...

Unfortunately, the referred link requires a Techconnect support contract. which has a cost. Contact your Rockwell local office, to see if they can help.
