Frequently Asked Questions about KV-16EX

Should I take cautions while using a serial port on the Keyence KV series unit?
When using a serial port on the Keyence KV Series Units of KV-16xx, KV-24xx, or KV-40xx there are percise precautions that need to be taken. These units provide two serial communication, called RJ-11 modular connectors. Unfortunatly, you should never connect  a ladder software and the handheld programmer to the two serial communication ports at the same time, but programs can be moved and observed by using either of the two serial communication ports.
When installing the Keyence KV-16EX programmable expansion PLC unit, what are some environmental locations that should be avoided?
When installing any Keyence unit, there are a couple environments that should be avoided for the protection of the data and the unit itself. Never install the Keyence unit outside or in direct sunlight, locations in between 0 to 50 degrees Celcius are allowed. Humidity levels in between 35 percent to 85 percent are also okay for this unit, but never in locations with dramatic temperature or humidity fluctuations. Installation near flammable or corrosive gases, dust, salt, iron power, soot, water, oil, chemicals, or near a strong magnetic or electrical field is not recommended. Also locations that may be subject to impacts or vibrations of any kind would not be suitable for this Keyence unit.
