PLC types
 If the output string is longer than the length defined for the output
variable (output_string) in the field "Type", only as many characters

special internal relay R9009 (%MX0.900.9) is set.
 The number of steps may vary depending on the PLC and parameters
used, see also Table of Code Intensive Instructions in the online help.
