S7-300 Modbus RTU -> Master - Slave

[naturephoenix]

Hi,
I would like to test my program according this manual:
https://support.industry.siemens.co...for-s7-300-and-et-200s-systems?dti=0&lc=en-WW

My problem is that from Hardware I have 1 part missing, thats DONGLE for CP341

So I got S7-300 CPU, CP341 (modbus master), ET200S CPU, Modbus rtu 1S module for ET200S .
I'm missing CP 341 dongle.

IS there any way to test my program even in demo mode for 10 mins or something without DONGLE

From memory, modbus works, but you have red error light on CPU without license.

see page 40. and error code W#16#A090

according another manual you can't load drivers to CP341 without dongle. You have to test
