Hello, I've got a problem with the SEND block of the PROTOCOL FB's, I need to calculate the checksum according to CRC-16 algorithm with initial value 0x0000, but the only available option is CRC-16 (Modbus) where the initial value is 0xFFFF. Is there a way to change the initial value, or add this checksum algorithm? Another problem is the order bytes in the calculated checksum, maybe you could add an option to swap bytes?
