[Bro] Is there existing signatures for modbus and dnp3

[Ren, Wenyu]

Dear all,

I am wondering whether there is some existing signatures of Bro for Modbus and DNP3. I found something named quickdraw, which are signatures for Modbus and DNP3. But it is for Snort and Bro does not support signature for Snort anymore as far as I know. Does anyone know some similar signature available for Bro? Thanks a lot.
