Connecting the Unit to Sensor Amplifiers Before Using the Unit This section describes how to mount a DL-RS1A and connect it to sensor amplifiers. (5) Alarm indicator This indicator lights up in red. For information on the actions you should take when an alarm occurs, refer to "Troubleshooting" (page 21). After turning on the power, the alarm indicator lights for the following amount of time, and communication cannot be performed during this time. No.
Connecting the Unit to Sensor Amplifiers Connecting the Unit to Sensor Amplifiers *2 Connecting the Unit to Sensor Amplifiers You use DL-RS1A by connecting it to sensor amplifiers. The connection method varies according to the mounting type of the sensor amplifiers. Before connecting DL-RS1A, you must install the main unit and expansion units of the sensor amplifiers. For information on installing the sensor amplifiers, refer to the user's manual supplied with the sensor amplifiers.
Connecting the Unit to External Devices Connecting the Unit to Sensor Amplifiers ■ Connecting the unit to panel mount sensor amplifiers 1 Connect DL-RS1A to the sensor amplifiers using the optional expansion cable (OP-35361). Communication Terminal Block You can connect external devices such as a PC or PLC to the communication terminal block of DL-RS1A via the communication cables.
Connecting the Unit to External Devices Connecting the Unit to External Devices ■ Connection wiring Sample wiring Refer to the connection wiring diagram shown below when connecting DL-RS1A to an external device such as a PC.
Communication Specifications Commands and Responses This section provides the communication specifications of DL-RS1A and describes how to configure the unit. Overview of Commands and Responses Communication Specifications ID No. 00 01 02 04 05 Main Exp. Exp. Exp. Exp. Command or DRQ input The following table lists the communication specifications for DL-RS1A.
Commands and Responses Commands and Responses Response Error response When DL-RS1A successfully receives a command from the external device, it automatically returns a response based on ASCII codes. For information on the parameters used in the response, refer to "Parameters of Commands and Responses" (page 10). If DL-RS1A could not receive a command from the external device or if the received command included an error, it automatically returns an "error response" based on ASCII codes.
Commands and Responses Commands and Responses Read with external input to the DRQ terminal (DRQ read) Reading You can send an input signal (by short-circuiting DRQ (terminal number 6) and SG (terminal number 1, 4, or 5)) from an external device such as a PLC instead of sending a command. External devices such as PLC's use the following communication commands to read data from DL-RS1A. Read from the specified sensor amplifier (SR command) Input signal SG Command RD ON SD S R ID No.
Parameters of Commands and Responses Commands and Responses This section describes the parameters used with various commands and responses. Writing Communication commands External devices such as PLC's use the following communication commands to write data to DL-RS1A. Point Attempting to write data with "read-only" attribute results in a communication error and an error response (error number: 22). There are two types of communication commands: read commands and write commands.
Parameters of Commands and Responses Parameters of Commands and Responses Data numbers Data No. Data name Data format*1 Specify the data number using three digits (ASCII characters). z Read-only data 061 Correction result*12 193 Product code No.
Parameters of Commands and Responses Parameters of Commands and Responses Convert the 2-digit number (ASCII characters) read to a binary number and check the ON/OFF state of each bit to check the judgment output status and check output status. Judgment output Bit 0 1 2 3 When N.O. 0: HIGH judgment output OFF, 1: HIGH judgment output ON 0: LOW judgment output OFF, 1: LOW judgment output ON 0: GO judgment output OFF, 1: GO judgment output ON 0: Check output OFF, 1: Check output ON When N.C.
Parameters of Commands and Responses Parameters of Commands and Responses z Read/write data The following table lists the types of data that can be read from and written to IB Series sensor amplifiers. Point When data is written while the initial reset is being performed, the parameter error will occur (Error number: 22). When writing data after the initial reset is performed, confirm that the EEPROM writing result (Data number: 053) shows "1: Normal termination" and then write data. Data No.

Parameters of Commands and Responses Parameters of Commands and Responses *7 If the the setting is changed between the 1st execution request and the 2nd execution request, correction cannot be made. When making correction, do not change other settings midway. Also, the auto adjust function does not work between the 1st point execution request and the 2nd point execution request. Make sure to perform the 2nd point execution request next after the 1st point execution request.
Communication Response Time Parameters of Commands and Responses Error numbers This section describes the communication response time for each communication command and various time frames. The following table lists the error numbers that are returned as error responses when errors occur in the communication with the IB Series. Each error number is identified with two digits (ASCII characters).
Communication Response Time Communication Response Time DRQ input The data read in response to a DRQ input is the buffered data that DL-RS1A periodically retrieves from the sensor amplifiers. Therefore, the latest data detected by the sensors can only be read after T2 (DL-RS1A data processing time) where DL-RS1A retrieves data from the sensor amplifiers. Time Frames of Communication Response Time This section describes the communication time frames (T2 to T6).
Communication Response Time Communication Response Time T5 (Response send time from DL-RS1A) T6 (Sensor amplifier settings change time) The time required to send a response varies depending on the communication speed, data bit length, and number of bytes. For information on the communication settings, refer to page 2.
