They occur below UANA = +13.5 V. If UANA continues to fall, an I/O error is triggered. All percentage tolerance values refer to the relevant measuring range final value. The maximum tolerance values contain the theoretical maximum possible tolerances. The validity of the values is 12 months at least. The data refers to nominal operation (installation on horizontal DIN rail, US = 24 V). Please also observe the values for temperature drift and the tolerances under EMC influences.

To keep the current flowing through the potential jumpers of the analog terminals as low as possible, always place the analog terminals after all the other terminals at the end of the main circuit. (For the sequence of the Inline terminals: see also IL SYS INST UM E user manual or Inline system manual for your bus system). 6 Installation instruction Installing jumpers may influence the accuracy of the channels independently of each other. Without using jumpers the voltage channels have a high level of accuracy and the current channels have a low level of accuracy. Installing a jumper for a channel increases the accuracy of a current output. This also reduces the accuracy of the voltage output. Only install the jumper when using a current channel. Installing a jumper when using a voltage channel will not be indicated as an error. Changing the jumper will only take effect upon power up.

To ensure that the terminal can be operated in the ST data format, the output value representation can be switched to the "IB ST" format. 13.1 "IB IL" format The output value is represented in bits 14 through 0. An additional bit (bit 15) is available as a sign bit. The sign bit is 0 for the output value 0 V to 10 V. If the sign bit is 1, which corresponds to a negative value, the value 0 V (or 0 mA/ 4 mA) is output. 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 SB OV SB OV Sign bit Output value Bits 2 through 0 are not mirrored in the input data. 13.2 Significant output values in the "IB IL" format The terminal has two analog output channels, which are able to output voltages in the range of 0 V to +10 V or currents in the range of 0 mA to 20 mA and 4 mA to 20 mA with a resolution of 15 bits plus the sign bit.

These are either the values of the configuration upon delivery or a non-volatile stored configuration. Output behavior in the event of an error (failsafe) In the event of an error the outputs respond according to the parameterization (see "Parameterization" on page 17). That means the outputs hold the last value (HOLD, default setting) or they return to zero (RESET, can be parameterized). The data format and the behavior of the outputs in the event of an error can be parameterized non-volatile or volatile by a process data sequence during runtime (see "Parameterization" on page 17). 14.3 Output behavior of the voltage and current outputs Switching operation/state of the supply voltage UANA from 0 V to 24 V UANA from 24 V to 0 V Local bus stopped Local bus stopped Bus reset (e.g., remote bus cable break) UANA UL xxxx 14.4 Take the output behavior in the event of an error into account when configuring your system, especially a fail-safe behavior that was possibly parameterized twice (for the bus coupler and the analog terminal).

Bits 2 through 0 are available as status bits and are used to display and read the set behavior of the terminal (see "IN process data" on page 12). If an error is detected by the terminal, it is indicated by means of an error code in the first or second process IN process data word depending on the error type. Possible error codes are given in the following table. Error codes: Output data word (two's complement) hex 8010 8020 8040 Cause Remedy The jumpers for selecting the "high accuracy" Connect the jumpers correctly. range are contradictory (e.g., 0 mA to 20 mA and at the same time 4 mA to 20 mA). The error message is indicated on the corresponding channel only. The user parameterization cannot be stored. Carry out a power up. The error message is indicated on both channels. Error in the I/O voltage supply Check the voltage supply on the bus coupler. Check that the potential jumpers are connecting safely. Replace the terminal. Terminal is defective. Replace the terminal. An I/O error is triggered with codes 8020hex and 8040hex. The error codes overwrite the status bits (bits 2 through 0) with "0". 6655_en_06 PHOENIX CONTACT 16 IB IL AO 2/SF ... 16 Parameterization By default upon delivery, the terminal parameters are set as follows: Data format: Behavior of the outputs in the event of an error: The following terminal parameters can be configured according to your conditions using the process data: IB IL Outputs hold the last value (Hold) Data format: Behavior of the outputs in the event of an error (failsafe): IB ST Outputs are set to 0 (reset) In order to parameterize the terminal you must change to parameterization mode. Steps to be taken to parameterize the terminal: Step 1: Transmission of code 8030hex in the first OUT process data word. In bits 15 through 3 of the first IN process data word this code is acknowledged as a normal process data item. Step 2: Transmission of the parameterization code in the second OUT process data word. Bit bin hex 15 1 14 0 13 0 12 0 11 0 10 0 8 9 0 8 0 0 7 0 6 1 5 0 4 1 3 p3 5 2 p2 1 0 0 p1 X Where px are the terminal parameters: p3: Volatile or non-volatile (0: Volatile; 1: Non-volatile) p2: Data format (0: IB IL; 1: IB ST) p1: Reset behavior (0: Hold; 1: Reset) Both output data words must be written with a maximum time of 10 s between each other. This makes data consistency over two words unnecessary. The writing sequence is not important. If the time has elapsed, something else, differing from the parameter value, must be written in the two words. The parameter words must be kept for 2 s until the parameterization is accepted. Step 4: Acceptance of the value is confirmed in bits 15 through 3 of the first input word through mirroring of the code. No timer is required in the application as monitoring the input data is sufficient. When mirroring, note that bits 2 through 0 still indicate the current terminal parameterization in each word. As soon as the new parameterization is valid the corresponding parameter bit is set in the input data. Step 5: The terminal is in normal process data mode again. Prior to a new parameterization, the data on both output words must have changed. The orange O-S LED on the terminal indicates whether the original configuration is present or whether the active configuration differs from the default configuration of the terminal upon delivery. The LED is on if the default state has been parameterized (see also "Local diagnostic and status indicators" on page 6). 6655_en_06 PHOENIX CONTACT GmbH & Co.
