The bolts in question are 195HB so they would fail the min hardness requirement according to the spec

Thank you for your reply but I have been told in the ASTM A320 L7M standard there is a min hardness on the bolts of 200-235HB I just wondered if it is correct as they have told me it is in the ASTM A320 L7M latest spec in one of the sections i think its 6,2 not sure. I have not got the spec to...

Hi, could anyone tell me the min hardness for an ASTM A320 L7M bolt i can see the max is 235HB but have been told the min is 200HB is that correct.

Hi Have you checked the comms parameters in each device? baud, parity etc Regards www.plcprogrammers.co.uk

Hi I Know its a little late but I would look at adding a MAX232 IC to your pic circuit to simplify comms between PLC and PIC. www.plcprogrammers.co.uk

Hi Does anybody know the difference an AY13E and a AY13EU output module on a Mitsubishi A3N CPU system? I know that they are both 32 point relay output modules, I just wondered if theye are interchangeable. Thanks

Hi Can anybody tell me what cable I need to connect a Omron C1000h plc to a PC running Syswin. Thanks

Hi Take a look at this thread, you will find what you need there. http://forums.mrplc.com/index.php?showtopic=609 www.wolfelectrical.co.uk

Hi I am guessing that what you overheard was an application specific conversation. I.E maybe refering to strips of terminals labelled by the deisgner of the plant. www.wolfelectrical.co.uk

Hi Thanks for the reply, but I didn't want advice on FX but on F1 / F2. Anyhow, I have obtained the SC03 and the F2-20 cable and adapter that I was looking for and the job is now done. www.wolfelectrical.co.uk

Hi Anybody have the circuit diagram for the Mitsubishi SC-03 cable for programming the F1 PLC's. I have a F2-20GF1 interface ready to go, just need the cable. Any help would be great.

Hi Are you opening your project or file offline before going online? If you upload your program as a new file from an SLC it won't contain the comments. plcman www.wolfelectrical.co.uk

Hi What Country is your application In? Regards Plcman www.wolfelectrical.co.uk

Hi As I understand it, it probably is possible to use a USB key but it is also probably in breach of the license agreement. Regards plcman www.wolfelectrical.co.uk

Hi Can anybody tell me where I can get hold of the mx-component activex that allows me to send and recieve data to and from an fx PLC in VB6. Many Thanks Alan Edwards

Hi I know that a type B does exist, any inverter / drive system manufacturer includes reference to them in their docs, unfortunately they don't seem to be able to point to a manufacturer. My problem is futher complicated by the fact that I need a 100A RCD, any manufacturer who makes something...

Hi Can anybody tell me who manufactures a 'type B RCD', this is a type which is suitable for use on smooth DC. The type reference is not related to the tripping characteristic of a circuit breaker or combined circuit breaker / RCD. Any help greatly appreciated. Regards Alan Edwards

Hi Thanks, but I have a regs book aswell. Regards Alan Edwards

Hi Thanks, I am aware of the type's for MCB tripping characteristics, and I hadn't heard of any type for RCD's but Control Techniques, the manufacturers of the inverters have this stated in there docs for RCD's and when I questioned it they were addament. The device is indeed for earth fault...

Hi I have been working in a place that has had to reduce its power consumption from the grid until it can be upgraded. We have therefore installed a 100A generator on site, we have connected the lighting circuits and one machine to the generator supply. For the Regs we have installed a 300mA...
