Cqm1h-cpu21 manual

It fails the host link test in the NT21's servive menu. Ive pulled it out of the machine and put the old one back so they can run the machine for now and ive rigged up on my bench the CQM1H-CPU21 and a NT21 so I can have a play however Im struggling to get communication. Ive checked the cable works and the the NT21 works on different machines so i know theyre both ok. Ive checked the comm port settings match. Obviously the peripheral connection works as I can easily connect to the CX programmer.

Im thinking that Ive missed something in the transfer to the new PLC? Ive checked dip switches are the same and have tried dipswitch 5 in both positions. I did read in various online manuals of the DM values however this is getting out of my knowledge base, I had thought that everything I'd need like that would be in the transfer? Any help would be hugely appreciated and any brownie points I get for fixing this will be shared equally Posted 4 Aug See the following manual on Page What are your communication settings?

I agree it sounds like PLC settings are not set, would these settings not have transferred over with the program? Communication mode - Host Link mode. Baud rate - Set the same speed as set at the NT Stop bits - 2 stop bits. Parity - Even. Unit You need to be a member in order to leave a comment. Sign up for a new account in our community. Both require a TC number and SV; they are connected to multiple instruction lines and serve as an input and reset signal.

INT —— is also used to stop the pulse output. Any TC number can only be defined twice, that is, once it has been used as an operand field in a tempo instruction.

Once defined, TC numbers can be used as many times as desired as operands in other instructions. TC numbers range from to No prefix is needed when using a TC number as operand data in a tempo instruction.

Once defined as a timer, a TC number can be prefixed with TIM to be used as an operand in certain instructions. The TIM prefix is used regardless of the timing instruction used to set the timing.

Once defined as a counter, a TC number can be prefixed with CNT to be used as an operand in certain instructions. CNT can also be used regardless of the counter instruction used to set the counter. SV is between The decimal point is not entered. When activated, TIM measures in 0. The end flag of a counter turns ON when the PV reaches zero and remains there until the counter is reset.

CNT is reset using a reset input, R. Your email address will not be published. Friday, January 14, Derniers articles.

Determine which words are available for the work bits and prepare an allocation table for these according to their use. Draw the ladder diagram. Enter the program in the central unit. Using the programming console involves converting the program into mnemonic form.

Check the program for syntax errors and correct them. Run the program to check for runtime errors and correct them. After installation of the complete control system and when it is ready for use, run the program and make the necessary adjustments.
