Summation (M+P_SUM)

M+P_SUM
When the integration start signal (START) is TRUE, this function block performs integration processing to the input (IN) and
outputs (OUT_) the result.
Use M+P_SUM2_ to reduce the influence of information loss in the single-precision floating-point operation.
( Page 86 M+P_SUM2_)
M+P_SUM is used to keep the compatibility with existing programs.
