  • Page 6 Overview of the Block Description Calling OBs This section contains information about the organization blocks (OBs) in which the block being described must be installed. When using CFC, the block is installed in the cyclic OBs (cyclic interrupt) and automatically in the OBs listed in the taskbar of the block (for example, in OB100 for a hot restart).
  • Page 7 Overview of the Block Description I/Os of ... The I/Os represent the data interface of the block. Via these I/Os, you can transfer data to the block and fetch results from it. Table 1-1 I/Os of ... Meaning Type Default Type Attr.
  • Page 8 Overview of the Block Description ● Attr. (Attribute) Additional characteristics of the parameter when used in CFC. Input and output parameters that are not interconnected can have parameters assigned (input/output parameters only with online FCs). Output parameters cannot have values assigned and can be transferred in CFC by interconnecting them to an input of the same data type.

Function The IEPH block serves as the interface between a BATCH recipe step of the type RPH (recipe phase) and the user programs on the automation system for control and status information.
  • Page 10 BATCH interface blocks 2.1 IEPH The IEPH block allows the following status changes: Operating principle ● Allocate / Enable A recipe step can occupy the block by setting the identifier OCCUPIED = 1. It also enters an occupied information based on the batch name, batch number, the step number (UBA_NAME, UBA_ID, USTEP_NO) and, if necessary, the step monitoring time (STEP_T).
  • Page 11 BATCH interface blocks 2.1 IEPH ● Status word The reaction to user input is signaled at the USTAT_L status input of the user block which is interconnected with the IEPH block. The status, including other block information, is returned at output QUSTAT_L and is monitored by BATCH. The bit assignment is synchronized with the assignment at the SFC_CTRL block.
  • Page 12 BATCH interface blocks 2.1 IEPH ● Start lock The "Start lock" identifier in the status word or input "ILOCK" can be used to inform the BATCH block that start or resume is not desired. Note The start lock must have been set in IDLE state if the BATCH is to comply with the start lock.

  • Page 24 BATCH interface blocks 2.2 IEOP ● Continuous mode or bumpless changeover When operating in continuous mode, two recipe steps (time-based) successively use the same block without resetting this block between the steps. The block only reports the READY state at the end of the first cycle. BATCH then sets the status ID for continuous mode by setting input ICONT instead of terminating the block by setting ITERM.
