Modbus ASCII analyzer doesn't work

Hi,

I send the Modbus/ASCII message
:3A 30 37 30 33 30 30 33 35 30 30 30 31 43 30 0D 0A

and capture with IO Ninja Serial Tap

Its valid request holding register 0x53 from device 7

Modbus Analyzer is not able to parse this message

Why? is any settings a wrong?

Regards

Juri

BTW! same package parsed if its sent and analyzed in Modbus/RTU mode

You are right -- the ASCII mode got broken in v5.3 (after the introduction of the form UI). Will be fixed in the next service release. Meanwhile, please apply this patch:

modbus-patch.tar.xz

Just overwrite the .jnc files in /scripts/plugins/Modbus; let me know if this works for you.
