  • Page 12: Functions

    Functions 750-1632/000-100 4 Functions 4.1 Operating Modes The I/O module offers two operating modes: • Operating mode with one valve • Operating mode with two valves The operating mode of the I/O module can only be changed when the outputs stages are switched off.

  • Page 13: Operational Functions

    750-1632/000-100 Functions 4.2 Operational Functions Depending on the parameterization of the I/O module, the following functions and proper- ties may be available: • On target • Normal operation • JOG/TIP mode • Control of functions via digital inputs • Emergency operation •...

  • Page 14: Figure 6 Actual Value Curve In Normal Operation

    Functions 750-1632/000-100 4.2.2 Normal Operation The control current provided by the I/O module can be directly specified in the process image (output) via a setpoint. The I/O module represents the present actual value in the process image (input) as a current value or as a percentage of the nominal current.

  • Page 15: Jog/Tip Mode

    750-1632/000-100 Functions 4.2.3 JOG/TIP Mode In JOG/TIP mode, the valves are set manually. The actual value can only move within the valid setpoint limits. With corresponding parameterization, JOG/TIP mode can also be controlled via digital in- puts DI1 and DI2. A logical “OR” operator is applied to the digital inputs and the corre- sponding bits in the control byte.

  • Page 16: Tip Mode

    Functions 750-1632/000-100 4.2.3.2 TIP Mode TIP mode is a time-limited variant of JOG mode. The time limit can be set via a parame- ter. Figure 8: Actual Value Curve in TIP Mode Event Description/Behavior Set SPL_EN to “0” and set TIP mode is activated. Present actual value is held.

  • Page 28: Approaching The Substitute Value

    Functions 750-1632/000-100 4.2.9.2 Approaching the Substitute Value The substitute value can be approached in two ways: • “Hard” approach to substitute value: There is no ramp; instead, the parameterized sub- stitute value is output directly. • “Soft” approach to substitute value: The stop ramp is used to approach the substitute value.

  • Page 29: Exiting The Substitute Value Strategy Through Acknowledgement

    750-1632/000-100 Functions 4.2.9.3 Exiting the Substitute Value Strategy through Acknowledgement To exit the substitute value strategy, the fault must be eliminated, and the SPL_EN bit must be changed from 0 to 1. The acknowledgement must be performed separately for each channel. After acknowledgement, the channel is in normal operation.

    Appendix 750-1632/000-100 8 Appendix 8.1 Technology of Proportional Valves Proportional valves can be used to control the throughput of liquids or gases. The throughput is determined by a lifting armature that is pressed on the valve seat by a spring. Thus the valve is closed in its inactive state. A further component of the propor- tional valve is an electromagnet that consists of one or more coils.

    750-1632/000-100 Appendix 8.1.1 Adaptation of the Valve Parameters to the Overlap Types The following three types of overlap exist: • Negative Overlap: A specified flow of the respective medium flows even in the zero position of the valve. • Zero Overlap: The valve has a defined zero position and opens very quickly.

    Data Areas). Figure 47: Communication via Mailbox 2.0 Example: A sender wants to transfer 10 bytes (the character string “Hello WAGO”) to a receiver via a 4-byte wide channel. 8.2.1 Message The Mailbox 2.0 process packs the data into messages. A message contains a header and user data.

  • Page 78: Transmission Channel

    Appendix 750-1632/000-100 8.2.2 Transmission Channel To transfer a message over a narrow channel, synchronization between sender and re- ceiver is required. Therefore, the transmission channel is divided into a synchronization part and a data part. For synchronization, a so-called handshake byte (HB) is defined. The handshake byte oc- cupies the first byte of the transmission channel while part of the message is always de- livered in the remaining bytes.

    750-1632/000-100 Appendix 8.2.3 Communication Phases The Mailbox 2.0 mechanism defines the following two communication phases: • Synchronization • Data Exchange Only after successful synchronization from sender to receiver can the actual user data be exchanged. 8.2.4 Synchronization In the synchronization phase, the handshake byte is used in Control mode. A distinction is made between interpretation as signaling mode and interpretation as command ac- knowledgment mode.
