ECAT-2011H EtherCAT Slave I/O module
Table 4-2-1: Signed Integer representation as follows:
The negative output value is represented in two's complement (negated + 1).
Maximum representation range for 16 bits = -32768 to +32767dec

Table 4-2-2: Unsigned Integer representation as follows:
The output value is represented with 15-bit resolution without sign, therefore polarity detection is
no longer possible. Maximum representation range for 16 bits = 0 to +32767dec

Table 4-2-3: Absolute value with MSB as sign - representation as follows:
The output value is displayed in magnitude-sign format: MSB=1 (highest bit) in the case of negative
values. Maximum representation range for 16 bits = -32767 to +32767dec
