It can be installed in any CJ1-series PLC system. It is classified as a basic I/O unit, occupying 48, 64 or 96 I/O points, depending on the number of activated inputs. Always verify that the maximum I/O capacity of the CJ1 CPU is sufficient for the number of required I/O points. ■ Nomenclature Unit status indicators x RUN (green) x ERC (red) Sensor error indicators x 1 - 6 (red) Removable Terminal Block x Connections for Thermocouples 1 - 6 x CJ1W-TS561: screw terminal x CJ1W-TS561 (SL): screwless terminal DIP switches (remove terminal block for access) x Select input types (K-type/J-type) x Select filter functions x Select number of active inputs (1-6) Terminal Block latch x Slide down to remove x Slide up to lock ■ Characteristics Thermocouple input Number of inputs Measurement range Indication resolution Cold junction compensation - Accuracy Temperature value Data representation Indication accuracy * over full operational range (0 – 55 °C ambient temperature) Input response time (per active input) Input update cycle time (all active inputs) I/O refresh time (influence on PLC cycle time) Keep the thermocouple wiring as short as possible to avoid electrical interference. Shielded wiring is recommended. x When extending input wiring, always use compensation wires appropriate for the thermocouple type. x For activated but unused inputs, short-circuit the + and terminals, to prevent unstable readout on the other inputs. x Keep the input wiring away from power lines including AC power supply lines and high-power lines. Do not run the I/O lines in the same duct or conduit as power lines. x The input circuits are galvanically isolated from the PLC’s I/O bus, but there is no galvanic isolation between individual inputs. x Always ground the terminal on the Power Supply Unit of the PLC. In case of shielded sensor wiring, connect the shields to the same grounding point as the PLC.

Incorrect DIP switch setting Fatal error in the Unit. x Check the CPU unit for error codes. x Re-start the PLC system. x If the ERC LED is still lit, replace the unit. x Measurement of the corresponding channel is within range, or x Channel has been deactivated by DIP switch settings x Measured temperature out-of-range, or x Thermocouple broken wire Calibration data not found or incorrect. The Unit should be returned to OMRON for calibration. ■ DIP switches ■ Data representation 8 DIP switches are accessible after removing the front terminal block. Switch settings are processed at time of power ON, and should not be changed while the unit is powered. Default (ex-factory) setting is all switches ON, i.e. all 6 inputs are active and set to K-type thermocouple, with filtering at n x 100 Hz. Be sure to adjust the settings to your requirements before use. SW 1, 2 and 3 : Input type selection Any combination of input types (different numbers of K-type/J-type sensors) can be set. SW 1 2 3 State OFF ON OFF ON OFF ON Input type selection Input channel 1 is J-type Input channel 1 is K-type Input channels 2 and 3 are J-type Input channels 2 and 3 are K-type Input channels 4, 5 and 6 are J-type Input channels 4, 5 and 6 are K-type SW 4 + 5 : Input filtering (valid for all active input channels) Use filtering if the measured value is affected by the mains frequency or other sources of electrical interference.

Each input value occupies one word (16 bits) in the CIO area and is encoded as a signed integer, with a resolution of 0.1 °C. Examples: #0300 = #FF85 = Value #7AAA #7BBB #7CCC #8CCC ■ ‘Not Ready’ flag During initialisation after power-on, and in case of internal failure, a ‘Not Ready’ flag will be set in the PLC memory area A050 to A069 (Basic I/O Unit information area, refer to CJ1 Operation Manual W393 for details). The lower bit of each unit is the Not Ready flag; the error code indicated in the remaining bits is relevant for repair purposes only. While this flag is ON, the temperature sensor data indicated by the unit in the CIO area is invalid. Address A050 A051 A069 Create the I/O table in the PLC after changing the switch settings, to register the correct number of input words in the PLC CPU. The unit is registered as 48-point, 64-point, or 96-point input unit, depending on the number of 16-bit CIO words it occupies.

Sensor error, broken wire Measured value out of range (over max. Temperature) Measured value out of range (under min. Temperature) During initialisation after power ON, data of active inputs will be #0000 until the “Not Ready’ flag turns OFF. A055 Input words are allocated in the PLC’s CIO area as Basic I/O Unit, i.e. sequentially starting at the leftmost unit. See CJ1-series Operation Manual W393 for details. 76.8 °C -12.3 °C Measured values are updated in CIO memory in each I/O refresh cycle. The following values are to be interpreted as error codes: SW 6+7+8 : Input activation To prevent broken wire indication for unused inputs, and to reduce the number of input channels occupied in CIO memory, the number of required inputs can be set by SW 6+7+8. 768 (dec) = -123 (dec) = Bit 00 08 00 … 00 … 00 08 When Bit = ON Unit in rack 0, slot 0 is not ready Unit in rack 0, slot 1 is not ready Unit in rack 0, slot 2 is not ready … Unit in rack 1, slot 0 is not ready … Unit in rack 3, slot 9 is not ready Unit in rack 3, slot 10 is not ready ■ Unit cycle time The internal processing time for all measurements by the unit is determined by the number of active channels and the filter type. Unit initialisation Measure Cold Junction + Sensor error check Measure Channel 1 Measure Channel 2 * In these cases, more CIO words will be occupied than required for the active inputs. The remaining occupied CIO words will be filled with 0’s, and cannot be used as work bits. The cold junction compensation measurement and one sensor error check are executed each cycle. The cold junction measurement time depends on the input filter setting, whereas the sensor error check takes a fixed 40 ms. Example: If 4 inputs are active, and filtering is set to n x 50 Hz (response time = 80 ms): Each measurement cycle takes (4+1) x 80 + 40 ms = 440 ms.
