Hello Martin,

Thank you for your reply.

The Hytec  corporation has updated 8401module to 100Khz clock rate.  The voltage of trigger pulse is ok. The 8992 terminal block, 8002 carrier and SCSI cable are purchased from Hytec corp. The hardware and connection is no problem.

I noticed that “Hy8401” was used in your record DTYP field. But in my example, “Hy8401ip” was filled in DTYP filed. That means your Hy8401software driver and mine is different.

 

 

Sorry I forgot to tell you about my records:

record(ai,"FINLB01-DWCM:VOLTAGE") {
                field(DESC, "Wall Current Monitor (WCM)")
                field(DTYP, "Hy8401")
                field(INP,  "#C91 S0 @")
                field(SCAN, "I/O Intr")
                field(EGU,  "V")
                field(LOPR, "-10")
                field(HOPR, "10")
                field(PREC, "3")
                field(EGUL, "-10")
                field(EGUF, "10")
                field(LINR, "LINEAR")
                field(FLNK, "FINLB01-DWCM:CHARGE")}

record(calcout,"FINLB01-DWCM:CHARGE") {
                field(DESC, "Wall Current Monitor (WCM)")
                field(INPA, "FINLB01-DWCM:VOLTAGE")
                field(INPB, "25.6")
                field(CALC, "A/(B/1000)")
                field(EGU,  "pC")
                field(PREC, "0")
                field(FLNK, "FINLB01-DWCM:VOLTAGE-WF")}

record(waveform,"FINLB01-DWCM:VOLTAGE-WF") {
                field(DESC, "waveform of analog inp.")
                field(DTYP, "Hy8401")
                field(INP,  "#C91 S0 @")
                field(NELM, "24")
                field(FTVL, "USHORT")
                field(EGU,  "Rawdata")}

PS: card number "#C91" means: VME crate slot 9, ADC IP on socket A = 1, this makes 91.

Hello LIU

I have here an working example, used for a ICT charge measurement at the SwissFEL teststand here at PSI, a analog voltage from a box car integrator to a Hytec 8401 ADC. Please see below the part of the startup.scrip.
Could it be that you use a clock rate (clkr "15") witch is not possible? I use "14" and "15" is not documented. Make sure that your external pulse is high enough in voltage! For example 3.3 Volts is too low, I have experienced. 5 Volts is OK. And are you sure about the connection of your external interrupt? Do you use a terminal block with a SCSI cable to a Hytec transition module? Check for example here http://www.hytec-electronics.co.uk/DataSheetHtml/8201.html the connection. Every time a interrupt appears the red led (A...D, depends where you placed the ADC) on the 8002 carrier should blink.

For IP module A the external trigger is on SCSI connector 1 (lowest, on the bottom of the transition module) on pins 43 and 18.

XTrig1 High	RP2/A23	Skt1/43
XTrig1 Low	RP2/C23	Skt1/18

Good luck and best regards!

Hi, everyone

I have the trouble of Hytec 8401ADC’ working way. I can let it works well if I set the SCAN field to “1 second”. But if “I/O Intr" was set, there are no any responses. I use 10Hz/5V pulse to trigger Hy8401ADC. The driver was downloaded from SLS. So who can help me to let it works on interrupt way?

In my opinion, I think I made some wrong parameters in the function of Hy8401ipConfigure(…). I don’t know how to set the parameters of vector and interrupt state. In my example, I set ‘intl”=3, “inte”=1. Also I am not sure I need to change some switch on slots of VME or not.

 

They are abstracted from st.cmd :

#                                      slot int options

 IPAC6 = ipacEXTAddCarrier(&EXTHy8002, "8 6 10")

 

#-------- 8401 (Analogue Input)------------------------------------------------

#                                                      card,  slot,               ipsl,   intl,        inte,         aity,       clks,            clkr,       inhi,         samp,         spac,         trig

Hy8401ipConfigure (  60, IPAC6,    A,  3,    1,    0,    0,    15,    0,    100,    1,   100)

 

It is the record what I used:

record(ai, "Hy8401:ADC-01")

{

  field(SCAN, "I/O Intr")

  field(LINR, "LINEAR")

  field(EGUF, "10")

  field(EGUL, "-10")

  field(DESC, "ADC Site A Ch 0")

  field(PREC, "6")

  field(EGU, "Volts")

  field(HOPR, "10")

  field(LOPR, "-10")

  field(DTYP, "Hy8401ip")

  field(INP, "#C60 S0 @")

}

 

They are the output information of VME/IOC:

#                                      slot int options

 IPAC6 = ipacEXTAddCarrier(&EXTHy8002, "8 6 10")
