Need to purchase what hardware devices?
Can use the VB call module is best

CodePudding user response:

With PLC or IO module, alarm push power, or different voltage relay also assisted

reference 1/f, stupid dog flew first response:

with PLC or IO module, alarm push power, or different voltage relay also auxiliary

If only and computer link, if there is one parallel port, plus a triode, relays, soon, ok

CodePudding user response:

Just connect with computer,

I need application scenario is this: I now some customers are dye house, dye house need to use dye, generally speaking, there are nearly hundred kinds,
When using said material system (my system of a module), which dye when said, then the corresponding dye the above alarm lamp is flashing, so workers can quickly find the corresponding dye, and don't need to spend time looking for,

PLC this I won't, relay I buy from taobao a, also bought three alarm lamp, a power supply, used to test, and some time ago in a group of people said it would make this control and told me to buy the equipment, now how do not contact me again, is originally wanted to let the other side to come to help me fix, of course, there is a reward,

Will make the can contact me, QQ: 435822921, is ultimately need to be able to dock with the I VB development of the system,
This is just outsourcing,

CodePudding user response:

We can write software for many years, sometimes with hardware is the outsider,
You know use computer to control a servo motor rotation, but you let him and gear form a complete set, with a leather/transfer or gear, big small? To do the mold or the ready-made, what size, these events a, you're just a pile of scrap iron immediately, lame,

Sometimes not only impulses, finally also can not get the finished product,
Do good and save electricity, no computer, direct control, mobile phone do bad battery life is often a problem,

The hardware of stability is very important

CodePudding user response:

You want to estimate is that control system

CodePudding user response:

If with low voltage lamp, such as 6 v, 12 v, the relay can also be saved, just 3 diode driver

CodePudding user response:

reference 5 floor xiaoyao961 reply:

what do you want to estimate is the control system of

is

Use IO modules, each module can control 4 ~ 32 points, the RS485 communication, the number of modules on a line with best control within in eight
