Hi I have problem. I have the old system with S5 115U CPU 943 (with 2 TTY) which is connected with HMI Lauer PCS090 on TTY2 and it is working perfect. Now I`m making new same maschine whith same system, HMI Lauer which is connected with S5 115U CPU 943 B (with 1 TTY), I upload the same program to CPU and to HMI, only difference is that HMI is now connected to TTY 1 (becouse this CPU has only 1 TTY) could this be a reason why HMI is showing: -connection error- -wrong DB- What is the difference between CPU 943(with 2 TTY) and 943B (with 1)? Thanks |

In the single serial interface, the interface port uses AS511 protocol for communicationusing TTY signals. If there is a second interface, the SI2 (second serial interface) of the CPU couldbeconfiguredto communicate in different protocols such as point-to-point, ASCII, 3964R etc. May be your HMI is using some protocol other than AS511. Did you try connecting new HMI on the old CPU? |

Hi JMJ, thanks for answer. Thing is that we have on stock only this CPU. But normali S5 program that I put on this CPU with one SI is made for CPU with two SI and I think that protocol for this HMI is also AS511. I don t know what to do if problem is in CPU it is not a problem to buy a new. |

Hello Spud2408, Please check you S5 programm. Is it using FB51 (TDOP511) then it is AS511 protocol or is it using FB53 (FAP protocol, only SI2 interface)? Best regards, Wizard |

Hi Wizard, it is using FB50, does this means anything? |

As per my knowledge these are the blocks for TDOP communication for S5
Now, I do not know what FB50 is, what is the FB name? |

I find at Lauer site that tey have comm manual for PCS with S5 but it is in German. I do not undestand much German, but it look like they have their own blocks for communication. http://www.lauer-systeme.net/web/lauer_en.nsf/AllDocuments/56C0956211F4317AC1257380002FD9BD http://ft.beijer.se/files/C12572A600329472/972EAF32BD285600C125740100547693/91SIE_D.PDF May be someone who understands German can help. |
