When the control output ON time is less than 190 ms, the bit is set to “1” and the heater currentis held at the last current value.Note 2. “Spare” bits are always OFF.Note 3. When read in setup area 1, the status of the bits will be as follows:• Overcurrent: Last value held• Current hold: Last value held• HB error: Last value held• Display range exceeded: Last value held• Input error: Last value held• Heating and cooling outputs: Cleared• HB and HS outputs: Cleared• Alarm outputs: Cleared• Program end output: Cleared3-17Com DataSECTION 3 Communications Data for CompoWay/F and SYSWAY3-18SECTION 4SYSWAY (E5@J and E5@XFormat) CommunicationsProceduresThese communications procedures are supported to provide compatibilitywith the E5@J and E5@X Temperature Controllers.

No response will be returned to anode with a number outside of this range.Header codeThis is a 2-character alphabetic code that indicates the command type.Data codeSet “02” only when reading and writing alarm value 2.
Otherwise, set “01.”TextThis area contains read values, write values, or status data. The data depends on thecommand.FCSThis is the Frame Check Sequence.The FCS (Frame Check Sequence) is calculated by taking the exclusive OR of all characters from the @ character to the last text character and converting the result to ASCIIcharacters.TerminatorIndicates the end of the block format.The terminator is composed of “*” and CR (Carriage Return = H’0D).● FCS Calculation ExampleSYSWAYThe FCS (Frame Check Sequence) is calculated by taking theexclusive OR of all characters from the @ character to the last textcharacter and converting that 8-bit result into two ASCII characters.StartCommunicationcharacterunit numberHeadercodeData codeFCS@(40H) 0 (30H) 0 (30H) R (52H) X (58H) 0 (30H) 1 (31H) 4 (34H) B (42H)FCS = 40H +3 0 H +3 0 H +5 2 H +5 8 H + 3 0 H + 3 1 H = 4 B HThe calculation result (4B hex) is converted to ASCII and written to the FCS bytes.4 → 34HB → 42HThe + symbols indicate XOR (exclusive OR) operations.4-24.1 Data Format■ Response Frame@EndcodeCommuni- Headercationsunit num- codeberEndcodeNameFCSTextTerminator* CRDescriptionPriority10Parity errorThe sum total of bits whose received data is “1” does notmatch the set value of “communications parity.”111Framing errorStop bit is “0.”212Overrun errorAn attempt was made to transfer new data when the receptiondata buffer was already full.313FCS errorThe calculated FCS value is different from the received FCSvalue.4IC*Undefined errorThe header code of the command cannot be interpreted.514Format errorThe command length is incorrect.60DNon-executable command• The set value was written when the “communications writing” parameter was set to “OFF” (disabled).• The set value was written during AT execution.715Undefined data value• The write data is either outside the setting range or not anumerical value.• The data code is either outside the setting range or not anumerical value.800Normal completionThe command ended normally without error.---* The response format is unusual when an “Undefined error” has occurred due to an invalid commandSee the following diagram for details.Response Format when an “Undefined Error” Occurred@Communi- Headercationsunit num- codeberFCSTerminator* CR■ Communications DataCommunications FormatSYSWAYSetting(monitor)valueFour digits(decimal)Negative valuesIf the leftmost digit is “−1,” it is set to “A.”Example: −1999 → A999If the leftmost digit is “-,” it is set to “F.”Example: −10 → F010Decimal PointThe decimal point is removed.Example: 105.0 → 10504-3SYSWAYheader code.
