产品说明

无底板，靠模块间接口直接相联，然后再固定到相应导轨上。OMRON公司的CQM1、CJ1机就是这种结构，比较紧凑。的S7_300也如此，只是它还要接线插头，如要单独固定时，还得另定购固定支架。

有底板，所有模块都固定在底板上。比较牢固，但底板的槽数是固定的，如3、5、8、10槽等等。槽数与实际的模块数不一定相等，配置时难免有空槽。这既浪费，又多占空间，以至于有时还得用占空单元，把多余的槽覆盖好。

用机架代替底板，所有模块都固定在机架上。这种结构比底板式的复杂，但牢靠。用这种组合时，它的模块不用外壳，但有小面板，用组合后密封与信号显示。

内插板式:为了适应机电一体化的要求，有的PLC制造成内插板式的，可嵌入到有关装置中。如有的数控系统，其逻辑量控制用的内置PLC，就可用这个内插板式的PLC代替。它有输入点、输出点，还有通讯口、扩展口及编程器口。PLC有的功能，它也都有。但它只是一个控制板，可很方便地镶嵌到有关装置中。

Product description

Without bottom plate, it is directly connected by the indirect port of the module, and then fixed to the corresponding guide rail. OMRON's CQM1, CJ1 machine is this structure, relatively compact. The S7_300 is the same, but it also needs a wiring plug, if it wants to be fixed separately, it must also order a fixed bracket.

There is a base plate on which all modules are fixed. Relatively firm, but the number of slots on the bottom plate is fixed, such as 3, 5, 8, 10 slots and so on. The number of slots may not be the same as the actual number of modules. Therefore, empty slots are unavoidable during configuration. This is both wasteful and takes up more space, so that sometimes it is necessary to cover the extra slots with empty units.

A rack is used instead of a baseplate, and all modules are fixed to the rack. This structure is more complex than the baseplate type, but it is reliable. With this combination, its module does not have a housing, but has a small panel, which is sealed with a signal display after the combination.

Interpolation plate: In order to meet the requirements of mechatronics, some PLC is manufactured into an interpolation plate, which can be embedded in the relevant device. If some numerical control system, its logic control with the built-in PLC, you can use this plug-in plate PLC instead. It has an input point, an output point, a communication port, an expansion port and a programmer port. PLC has the function, it also has. But it is just a control panel that can be easily inserted into the device.
