User manual OMRON E5AR-T

[. . . ] H201-E1-01 E5AR-T E5ER-T Programmable Digital Controller USER'S MANUAL Introduction OMRON products are manufactured for use according to proper procedures by a qualified operator and only for the purposes described in this manual. This manual describes the functions, performance, and application methods needed for optimum use of the E5AR-T/ER-T Programmable Digital Controllers. Please observe the following items when using the E5AR-T/ER-T Programmable Digital Controllers. · This product is designed for use by qualified personnel with a knowledge of electrical systems. [. . . ] Addresses are two bytes long and written in hexadecimal. Addresses are allocated according to access size. Each address consists of a channel identifier and the address in the area. Address (2 bytes) 0 0 0 0 0 0 # # 0 A6 A5 A4 A3 A2 A1 A0 Address in area 00 to 7F: 128 variables Channel identifier (0 to 3) * Bits other than those for the channel identifier and the address in the area are used for variable types DA to F9. CompoWay/F Communications 6-8 6. 4 Variable Areas Channel Identifier To specify channels 2 to 4 for Controllers with more than one input channel, specify a channel identifier between 1 and 3 to identify the channel. Only 0 (channel 1) can be specified for Controllers with only one input channel. Channel identifier 0 1 2 3 Channel Channel 1 Channel 2 Channel 3 Channel 4 Address in Area This address is allocated a parameter in the variable areas. Addresses are assigned in order beginning from the first parameter. For more information on addresses, refer to Appendix Setting Lists (P. The addresses indicated in the setting list are the addresses for channel 1. To specify an address of channel 2, for example, add 0100 to the address in the setting list. For channel 3, add 0200, and for channel 4, add 0300. The number of elements is expressed as a 2-byte hexadecimal number. For example, if the number of elements is 0010, the first 16 elements of data (H'10) from the address are specified. The specification range for the number of elements depends on the command. 6-17) for more information. Set Values Values read and written to a variable area are expressed in hexadecimal and disregard the decimal point. Negative values are expressed as a two's complements. Example: D'105. 0 H'0000041A This variable is an 8-digit number in hexadecimal. Negative values are expressed as a two's complement. If the PV of the E5AR-T/ER-T is 105. 0, it will be read as H'0000041A (105. 0 1050 H'0000041A). Read/write data will be the same as display values when reading or writing data using the program time unit. For example, if the display value is 99. 59, the read/write data will be H'00009959. 6-9 CompoWay/F Communications Number of Elements Section 6 CompoWay/F Communications 6. 5 Read from Variable Area Read from a variable area by setting the required data in the following FINS-mini command text format. Command FINS-mini Command Text MRC "01" 2 SRC "01" 2 2 4 Variable type Read start address Bit position Number of elements "00" 2 "0001" to "0019" Data name MRC/SRC Variable type Read start address Bit position Number of elements Description Specify the Read from Variable Area FINS-mini command. Specify "00. " Specify the number of variables to read (max. Not needed for a compound read. Response FINS-mini Response Text MRC SRC "01" 2 4 Number of elements × 8 bytes (for compound read, number of elements × 10 bytes) Response code (MRES/SRES) Read data CompoWay/F Communications "01" 2 Data name MRC/SRC Response code Read data Description The FINS-mini command text is returned here. Data that was read. Response Codes Response code "1001" "1002" "1101" "110B" "1100" "2203" "0000" Error name Command length too long Command length too short Area type error Response length too long Parameter error Operation error Normal end Description The command is too long. Number of elements is greater than 25 (H'0019). [. . . ] *3: If this is PV or SP based on the PID Set Automatic Selection Data parameter, then (setting upper limit + setting range × 0. 1); if it is DV, then (setting range × 1. 1). *4: Initialized only if the control mode is changed to proportional control (Temperature: Initializes to upper and lower limits of sensor setting range. Analog: Initializes to values set for Scaling Display Values 1 and 2 parameters). *5: Upper/lower limit of sensor setting range and Scaling Display Values 1 and 2 parameters are initialized. [. . . ]
