Error testing the WebHMI

[nicolas.ard]

Hello there,
I have a device that have a Modbus TCP/IP server working good in port
8000.
I tried to put WebHMI in work, adding the device with the format
IpAdress:Port, and some variable to see, but when i clicked in "view"
it don't work.

I got the message (In the browser), (url: http://localhost:8075/modbus-read/5/1/3/200/16
)

[START MESSAGE]
Error 500: Internal Server Error

Sorry, the requested URL http://localhost:8075/modbus-read/5/1/3/200/16
caused an error:

Unhandled exception
[END MESSAGE]

in the console i got the message
localhost - - [11/Apr/2011 16:58:49] "GET /modbus-read/5/1/3/200/16
HTTP/1.1" 500 716

I have never used bottlepy, but i think that it's a problem with it.

Thanks

Cheers

Hello Nicolas,
The webhmi is somehow an experimental feature. It may have some troubles.
Can you try to modify the show_results function in master_webhmi.py and catch all exceptions. It will help you to understand what's wrong.
I hope it helps
Best

Hi Luc, thanks for your reply,

I found the bug, it's a problem with variable types, in the "Master" class

class Master:

    def __init__(self, protocol, address, id, db):

        

        if protocol == "tcp":

            

            try:

                (host, port) = address.split(":")

                 self.modbus = modbus_tcp.TcpMaster(host, port)

The variables in red must be casted, the host to string and the port to int. (Really only the port to int, because the split() function returns a array of strings, but to keep the thinks clear i put the cast in both variables.

So here it's the class solved.

class Master:

    def __init__(self, protocol, address, id, db):

        

        if protocol == "tcp":

            

            try:

                (host, port) = address.split(":")

                 self.modbus = modbus_tcp.TcpMaster(str(host), int(port))

Now works good, i'm using Python 2.6.4
