PLC Control
In Galvano plating plant automation systems, PLC systems are compatible with the increasing usage of the devices has become mandatory. MRS simple or complex about it a lot of different levels of alternative offers.Thus, the PLC system is used in the facility, no matter how necessary to comply with at least one of the alternatives will be enough. Below are given some information about the various options presented and its application. External On / Off Control: The simplest method of control. A normally open only to run the unit by the PLC is sufficient to release the contact. If the device turns on and the ignition switched on the ignition of the PLC closes the device stops.If the device status information to be taken in case contact is available on the device. Contact is in contact with this same feature of the PLC.The device is has contact the entire time it is on.Turn off the ignition device is stopped for any reason. If you are granted by PLC command to stop a problem, because even though the device seems to be easily understandable if the contact closed. External on / off control of voltage and current values of the device will operate must be set in advance, and only one. Length control is determined by the PLC does not need to make any adjustments. If you have made the necessary adjustment feature of the device ampere-hour counter, automatic dosing information is available via separate contacts.
External Program Selection: External On / Off control of external program selection feature to eliminate the restriction of a single program that can be used. 15 different programs can be defined in advance by the memory of the device and PLC 4 (2 ^ 4 = 1 + 15) with free to contact the desired program can be selected.All contacts to be open by the device "Stop" command is considered. In addition, the ignition is turned off for each program determined that the device turns on with the program. As an external on / off the device status information such as contact of the device status can be taken. External program selection with a relatively economical solution compared to other systems is provided. Users can define process in accordance with the program for 15 different tracks. Thus, automation control system, the program has been operating the program through the device is desired.Current-voltage setting or automation system needs to be replaced by a broader range of current data to be taken by the device should be used in applications other advanced options. |
