Hi there I have a simple question about IO-R08 module output LEDs. I have a V700 with attached expansion and IO-R08 modules. The intent is that the relays will pulse process pumps at up to 9Hz during scheduled and manual sessions, Everything appears to be working, however I am about to deliver to the customer to install with the pumps and i notice an odd beahviour of the output LED indicators on the relay module. When I pulse the relays, the LEDs pulse - but inconsistently. If I pulse at, say, 1 to 3 Hz the LEDs appear to be pulsing at the same rate but as I increase frequency up to 9Hz the LEDs appear to have a more random nauture to their relationship to the actual relay frequency. Should the LEDs represent exacly what the relay is doing, partcularyly at the upper end of their range - 9Hz? See short vid of all relays firing at 9hz - the output LEDs dont fire consistently. any thoughts or guidance greatly appreciated. Thanks, Mal IO-R08 at 9Hz.MOV
Hello~ I have some doubts about ADC program of the hardware between STM8S103F2 and STM8S105,if you can give me some feasible advice,I’ll be appreciated. Thank you in advance! Please look at the following picture, why the ADC program of STM8S103F2 cannot use in the STM8S105C4T6? And the collective result always be zero. I am so confusing about that ! The datasheet of STM8S105C4T6 Are there any wrongs I set? Please tell me the reasons and solutions,thank you again ! Well,If I choose the wrong forum to ask my questions,please forgive me and tell me which forum is suitable for asking my troubles. Best regards~
Hi @ all, I have just a short question about the hardware of a V260-16-B20B. When reading the installation guide, there is stated, that the COM2 Port could be used either as RS232 or RS485 port. One should be able to choose if it's 232 or 485 by changing jumpers on the inside of the OPLC, right next to the COM-Ports. As I opened the OPLC to install an Ethernet-Card on Port3, I wanted to change the COM2 Port to RS485 by jumper selection, but there is none .... So, is it not necessary to have jumpers switched on V260-16-B20B or is it not possible to use it for RS485 Modbus Communication on Port2 ??? Thanks to you guys, FireNeck
