SECTION 4 SYSWAY (E5@J and E5@X Format) Communications Procedures
4-4
■ SYSWAY Command Lists
• No commands will be accepted and no responses will be returned when a memory error (RAM error)
has occurred or during initialization (until the process value is recognized after power is turned ON).
• When a write operation is performed while there is a memory error (EEPROM error), data will not be
written and the command will end with “normal completion.” Read operations will be executed
normally.
Note 1: The number of EEPROM (non-volatile memory) write operations is limited. Therefore, use RAM
write mode when frequently overwriting data.
Note 2: The process value read range is the same as the input’s display range.
Note 3: Status (last 4 bytes)Note 4. Status (first 2 bytes)
• Overflow: Set 1 when the heater current value is greater than 55.0 A.
• Display hold: Set 1 when the control output ON time is less than 100 ms. The previous heater current
value is held.
