*1: Refer to the HWCONFIG settings in ISPSoft for the user-defined baudrate.
*2: Refer to section 6.19.3 for the use of communication flags and registers.
6. Clearing the device contents
 SM203/SM204/SM205
Device number
SM203/SM204
All non-latched areas are
cleared.
SM205
All latched areas are cleared.
Refer to Section 2.1.4 for more information on the latched areas in the device range.
7. PLC error log
 SR40-SR161
SR40: The maximum number of error logs stored in SR40 is 20. If the number of the error logs exceeds the
maximum number 20, only 20 of them will be stored. Each error log occupies 6 registers.
SR41: The error log pointer points to the latest error log. When an error occurs, the value of the error log pointer
increases by one. The range of pointer values is 0–19. For example, the error log pointer points to the fourth error
log when the value in SR41 is 3. If the value in SR41 is 20, that means the number of error logs exceeds 20 and is
now in cycle.
SR42~SR161: The time of the error and the position where the error occurs are recorded in SR42–SR161. The lsot
column records the CPU (0) and the remote module number (1~15). The following table lists the corresponding
functions of these data registers.
