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 !

commented

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"

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.

commented

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.

commented

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){
				
				})
})
commented

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

commented

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

commented

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

commented

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

@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
