EN2SE-R Generic Serial Configuration

Anybus Support Anybus Gateways
#1

I am working on a project that requires sending ascii data through serial. No frames, no delimitters, no CRC, just plain ascii data

I have setup an HSM-EN2SE-R as generic serial to achieve this.

The data is only 12 strings of 24 characters each, and I have the CompactLogix sending the data and I am able to see it in the Node Monitor (all the data show properly on the map) but I am not able to see it with terminal on my PC (putty). I also see the transmission counter going up in the PLC tags.

I am connecting the PC through a null-modem cable to the gateway and I am not getting any red leds from it either. Both serial configuration parameters are the same (terminal and gateway).

I am uploading the configuration file

WITS_L0 Config File Rev 1.cfg (16.0 KB)

What am I doing wrong?

You have the Control/Status word enabled, so you will need to write to the Control word in order to start the subnetwork. I would recommend disabling it to see if you see the data then.

Did you try disabling the Control word? Did that fix the problem?

Hi Kyle,

Unfortunately I haven’t tried yet. The Rig left last Friday and will arrive to Oman next week.

I will be travelling there over the weekend and start commissioning pro la my next Wednesday.

I will let you know then.

Thanks,

Hi Kyle,

Worked on this yesterday all day and did not have any luck on RS232. I tried everything, null modem cables, straight 1 to 1 cables, breakout boxes and nothing. Checked my 2 RS-232 USB dongles with one of the null modem cables and I was able to write between the two terminals (teraterm) on my pc.

Last night I changed the configuration to RS485 and used my RS485 USB dongle and it worked the first time.

To be honest I don’t understand what was the issue.

Do you have any ideas what the problem might be?

Thanks,

Hard to say exactly. Make sure to check:

  1. Subnet parameters are correct in the Anybus:

  2. Pinout is correct:

Also check with pinout on the USB dongle.

You may want to try swapping RS232 Rx and Tx lines.

Hi Kyle,

The subnet parameters are the same for RS232 and RS485 with the exception of the serial network.

I checked the Pinout for RS232 for the dongle and null modem cable and it was correct as well.

Like I said I don’t understand what the problem was

This is very strange indeed. Do you have the PC (w/USB dongle) and Anybus directly connected with a DB9 cable (no hubs)?

Do you have Flow Control in Putty disabled?

I’m running out of ideas on this. It should be very simple. We may have to resort to replacing the device.

Can you send me your latest cfg file?
