Macro activation problem on Brick LV power on

[jnasri]

Hi all,

 

I am having some trouble with the Macroactivation on power on of a Brick LV:

 

The hardware setting is as follow: 1 Powerbrick LV as Master & 1 Powerbrick LV as Slave.

 

the config of the Master

PowerBrick[0].MacroModeA =$00403000;

PowerBrick[0].MacroModeB =$00000000;

PowerBrick[0].MacroEnableA =$0FFFFF00;

PowerBrick[0].MacroEnableB =$0;

 

PowerBrick[1].MacroModeA =$0;

PowerBrick[1].MacroModeB =$0;

PowerBrick[1].MacroEnableA =$0;

PowerBrick[1].MacroEnableB =$0;

 

Macro.TestPeriod =10/Sys.ServoPeriod;

Macro.TestMaxErrors =Macro.TestPeriod/10;

Macro.TestReqdSynchs =Macro.TestPeriod-Macro.TestMaxErrors;

Macro.IOTimeout =0;

 

config of the slave

PowerBrick[0].MacroModeA =$00408000;

PowerBrick[0].MacroModeB =$0;

PowerBrick[0].MacroEnableA =$0FFFFF00;

PowerBrick[0].MacroEnableB =$0;

 

PowerBrick[1].MacroModeA =$0;

PowerBrick[1].MacroModeB =$0;

PowerBrick[1].MacroEnableA =$0;

PowerBrick[1].MacroEnableB =$0;

 

Macro.TestPeriod = 10/Sys.ServoPeriod;

Macro.TestMaxErrors = Macro.TestPeriod/10;

Macro.TestReqdSynchs = Macro.TestPeriod-Macro.TestMaxErrors;

 

Randomly on power on , the master macro status never pass to Active.

I have the following macro status:

on the On master:

Macro.status[0].active=0

Macro.Status[0].SynchMaster =1

Macro.Status[0].TestEnabled=0

On the slave:

Macro.status[0].active=1

Macro.Status[0].SynchMaster =0

Macro.Status[0].TestEnabled=1

 

 

 

From the master side, I issued some line command as follow:

Macro.RingTest[0].PwrOnErrCntr

Macro.RingTest[0].PwrOnErrCntr=0

Macro.Status[0].RingError

Macro.Status[0].RingError=0

Macro.Status[0].ErrorsFault

Macro.Status[0].ErrorsFault=0

clrf

stdin:6:5: error #50: MACRO COM TIMEOUT: clrf

Macro.RingTest[0]

stdin:7:2: error #20: ILLEGAL CMD: Macro.RingTest[0]

Macro.Rings

Macro.Rings=1

Macro.ICs

Macro.ICs=4

Macro.IC3s

Macro.IC3s=2

Ldata.CmdStatus

Ldata.CmdStatus=0

Macro.RingTest[0].RingBrkStationNum

Macro.RingTest[0].RingBrkStationNum=0

MacroControllerDetect

Error: PowerBrick[0] isn't in a connected Ring

Error: PowerBrick[1] isn't in a connected Ring

MacroControllerDetect

Error: PowerBrick[0] isn't in a connected Ring

Error: PowerBrick[1] isn't in a connected Ring

 

 

 

When I disconnect/ reconnect the fiber optics With the brick lv powered on the status of the macro change to active.

 

Please help me to diagnose the problem.

 

Best regards

Try setting PowerBrick[0].MacroModeA =$808000 on the Slave. Copied from the Power PMAC User manual:

 

Slave IC

An IC used as a slave on the ring, as in a Power Brick drive used as a slave device, should have bits 12 and 13 both set to 0 to disable any master functionality. Bit 15 should be set to 1 to lock in the IC’s phase clock on receipt of the sync packet. Bit 23 should be set to 1 to disable the “master-number check” on the Node 23 packet. This means that Gate3.MacroMode should be set to $808000 for this IC (Node 15 master-number check disable, sync packet receipt lock).

I tried your suggestion : "PowerBrick[0].MacroModeA =$808000 on the Slave".

 

unfortunately it doesn't change the activation pb on power on of the master side.

 

on power on:

slave side: i have auxslaveconfigfault ( see Slavestatus2.png)

PowerBrick[0].MacroModeA =$808200

 

on the master side: see MasterStatus2.PNG

 

note: the macro status leds are green on both sides ( master and slave).

One workaround is to issue MacroControllerInit from a PLC until the ring is active. Something like:

 

GLOBAL MacroInitCtr

 

OPEN PLC MacroInitPLC

MacroInitCtr = 0

WHILE(Macro.Status[0].Active == 0 && MacroInitCtr < 10)

{

CMD"MacroControllerInit"

CALL DelayTimer.msec(1000)

IF(Macro.Status[0].Active == 1){DISABLE PLC MacroInitPLC}

MacroInitCtr++

}

DISABLE PLC MacroInitPLC

CLOSE

 

Also, note that:

- It is recommended to only enable used nodes

- Node 14 on the slave should be left off, PowerBrick[0].MacroEnableA =$0BFFFF00

[jnasri]

I added MacroinitPLC and changed the PowerBrick[0].MacroEnableA value to $0BFFFF00 on the slave

 

but the following command that i use in one of my PLCs didnt repond : macro timeout

MacroAuxiliaryRead 0,P555, P556

 

it responds only if the PowerBrick[0].MacroEnableA = $0FFFFF00 OR PowerBrick[0].MacroEnableA = $0FBFFF00

 

 

I added a ctr to see in how much time the active status is reached and it is about 30 second +/- 20 seconds

 

i added also a ctr to see in how mush time the MacroAuxiliaryRead Command is successfull and the result is 5 to 30 retry ( 1 second between each command)

 

do you have an explanation for that?

[Richard Naddaf]

$0FBFFF00 is correct. $0BFxxxxx was a typo.

 

We have seen this issue with the UMAC counterpart accessory (ACC-5E3). It turned out to be a hardware ECO.

 

We had not seen it with the Brick series, but it may be susceptible to environment and installation conditions. I have already asked the design team to look into it.
