To and From CMD in Mitsubishi

[ZHLakra]

Hello Guys,

have been in this industry for 8 years, and working on Mitsubishi for the first time,
totally confused with the "to and From CMD.

i want to sent and receive the IOs to Fanuc robots, over cclink

the reference that i have in that they are using "from and TO" cmd for it.

[from     H0     H71E     K4x8c0     k6]

the robot IO range is X/y8C0-91F.

i understand that K, and H are just constant, but what and how did this 71E come from, 

Please help me out understanding

sounds like you are working on an old A series plc.

With the TO FROM instructions you can exchange data between the CPU and a special module.

In this case the first module in your system as the first value is H0. The second one is the location on the special module called BFM buffer memory. H71E hex 71E.

the third part K4 means 4 x 4 bits starting from X8C0 (input 8C0). and the last 6 means to continue this for the next 5 aswell.

So you are sending

X8C0..X8CF to BFM hex71E

X8D0 .. X8DF to BFM Hex71F

etc.

you are right its a old Q type Cpu, 

adding more Mig robots, but cclink, trying to get an idea of how the IO communications works on this.

 

Appreciate the knowledge and time

Q like QnA than if it is a system Q CPU you don't need to write any code

There are some free trainings on CC-Link. just google e-learning Mitsubishi
