1. Mitsubishi PLC (Introduction FX Series)
Enter the address is to X1, X2, X3, etc., the output is Y1, Y2, Y3, as long as the programming and wiring consistent, and the computer connected with SC-09 line, Genuine with grounding line is 350 yuan, the program Download to the computer DIP switch to ON, the program downloaded to the PLC on the OFF, should not be downloaded to the PLC after the dial to the ON or not output.
The basic instructions are LD AND OR SET RST TIME C, etc., in fact, is the relay circuit, if you use PC programming without mnemonics.
2. Omron PLC (Introduction CQM1, CPM1A, CPM2A)
CQM1 address is entered as 0.00, hexadecimal, such as five input module is 0.00-0.15 is a 1.00-1.15 is a until 4.00-4.15, the output starts with 100.00, 16 into, there are five, that is, 100.00-100.15, 101.00-101.15 until 104.00-104.15
CPM1A.CPM2A Input Same as CQM1, output starts with 10.00.
Their internal relay to 200.00 at the beginning, if only five output modules, can also be 6 for the internal relay, such as 106.00,16.00. Time relay to 0.1 seconds, and Mitsubishi
And computer connection, with CIFO1 line, the mouth is the printer interface .20 pin. Note that the computer behind the two ports, the left is COM02, COM01 line price is 550. CPM2A 232 interface.
Programming software CX-PROGRAMMER, programming, note that if there is a red line is wrong. Mode also pay attention. There is no output in programming mode
3.AB PLC (Introduction LOGIX5555 controller)
Unlike the above PLCs, AB focuses on tags, types of data, and memory
First of all, to configure the output programming input module, the type of module is marked on the controller, such as the 1756 module, you have to configure the module, or can not be uploaded (each module requires the corresponding authorized disk, the authorized disk is Use files to encrypt, the general use of the disk, can not use a removable hard disk, only with the HD-COPY software on the disk program)
Address input Local: 1: i.date1, is the first module input 1, LOCAL: 1: I. DATE2 is the module 1 input second, the output is LOCAL2: O. DATE1, module 2 output first
Time in milliseconds, a and b can be defined as internal relays, such as a1.0 and b2.0 and so on.
