BK9050

Hello,

I'm trying to connect to BK9050.

Without bareClient actived this is what I got during the connecting process:

By setting bareClient to true, it seems able to connect to the device but right after the connection, I got this error:

This is happending when I try to read this register: group:16416 offset:2 length:1

Do you know why I get this error ?

Thanks for your help !

[ptorrent]

For your information, I'm using an export of symbols:

<PlcProjectInfo>
	<RoutingInfo>
		<AdsInfo>
			<NetId>192.168.1.232.1.1</NetId>
			<Port>100</Port>
		</AdsInfo>
	</RoutingInfo>
	<Symbols>
		<Symbol>
			<Name>KL6781-0000_1_Channel_1.State</Name>
			<Type>UINT</Type>
			<IGroup>61472</IGroup>
			<IOffset>0</IOffset>
			<BitSize>16</BitSize>
		</Symbol>
...

I'm trying to subscribe to the symbole name and I got this error "Index out of range".

So I tried to get raw value with groupIndex and offset but same error !

The result of a read is: (buffer is the value, USINT is the datatype from export )

04-09-2023 20:15:58.997 > error > ads_24 > <Buffer 00> USINT
04-09-2023 20:15:58.997 > error > ads_24 > <Buffer 00> USINT
04-09-2023 20:15:59.009 > error > ads_24 > <Buffer 00> USINT
04-09-2023 20:15:59.009 > error > ads_24 > <Buffer 00> USINT

	client.readRaw(61472,0,2).then(function(res){
					console.error(res,'UINT')
					client.convertFromRaw(res, 'UINT').then(function(value){
						
					}).catch(function(err){
						
					})
				}).catch(function(err){

				})

The issue seems coming from "convertFromRaw"

[jisotalo]

Could you please show the Node.js code you are using with connection settings?

Quickly looking the port could be also 300 (https://download.beckhoff.com/download/document/io/bus-terminals/bk9000_bk9050_bk9100en.pdf):

Edit: And yes most probably these BK systems have no system manager so bareClient is the correct/only option.

Thanks for your answer, this is my settings:

 var settings = { 
	localAmsNetId: '192.168.1.110.1.1',
	localAdsPort: 32905,
	targetAmsNetId: '192.168.1.232.1.1',
	targetAdsPort: 300,
	allowHalfOpen: true,
	bareClient: true,
	readAndCacheSymbols: false,
	routerAddress: '192.168.1.232',
	routerTcpPort: 48898 
}
client = new ads.Client(settings)
client.connect().then(function(err){
		client.subscribe("KL6781-0000_1_Channel_1.State", (data, sub) => {
			console.error('change')
		}, cycleTime).then(function(sub){
			console.error('success!')
		}).catch(function(err){
		        console.error('failed !',err)
		})
})

I don't receive Change / success! / failed! log. Just:

I am able to read the value but not decode it. Seems that i'm also able to subscribe to the symbol name, but still same error. However, I feel like I'm only receiving 00 Buffer or 00 00 depending the length.

[jisotalo]

What happens when you try to read it using indexGroup and indexOffset with readRaw()?

I'm not too familiar with BK9050 and I don't have any unit to test myself.

[ptorrent]

I'm able to get the value: Buffer(00 00)

client.connect().then(function(err){
                             client.readRaw( target.group,target.offset,target.length).then(function(res){
					===> OK I've the res

					===> crash the process on convertion
					client.convertFromRaw(res, target.type).then(function(value){
						
					})
				}).catch(function(err){
				
				})
})

[jisotalo]

Is the value correct? Can you get a value that isn't 0?

[ptorrent]

I will check it tonight and let you know, not at my desk, thanks for your support

[ptorrent]

Hello again, I was able to decode value by adding this in ads-client.js line 6049:

try{
  switch (packet.ams.adsCommand) {
....
  debugD(`_parseAdsData(): ADS data parsed: %o`, ads)
} catch(e){}

values are correct

[ptorrent]

But with that solutation, cannot read value with readSymbol because of this error and readRaw for BOOL type:

I think that catching the decode error remove some properties needed for decoding value

ClientException: Reading data failed (Cannot read property 'byteLength' of undefined)
line 1442

Others types working fine, UINT etc...

If you want to check a bit, I can give you access to the linux machine. We can pay for your support as well

[jisotalo]

@ptorrent can you send me email. You can find the address from package.json details for example.

Issues related to this are now fixed in 1.14.3
