Function blocks of the ET 200S 1SI serial interface
module
3.1

Overview of function blocks

This section describes all of the function blocks (FBs) required for communication between a
SIMOTION hardware platform and a serial interface module.
The function blocks form the software interface between the SIMOTION hardware platform
and the serial interface module. They must be called repeatedly (in cycles) from the user
program.
The following function blocks are available for the 4-, 8- and 32-byte data interface of the
ET 200S 1SI serial interface module:
● Function blocks _ET200S_SIxx_send (Page 19)
● Function blocks _ET200S_SIxx_receive (Page 23)
● Function blocks _ET200S_SIxx_getV24Sig (Page 27)
● Function blocks _ET200S_SIxx_setV24Sig (Page 29)
● Function blocks _ET200S_SIxx_flowXon (Page 30)
● Function blocks _ET200S_SIxx_flowRts (Page 32)
● Function blocks _ET200S_SIxx_flowV24 (Page 34)
Note
xx stands for 04, 08 and 32, e.g.:
● Function block _ET200S_SI04_send
● Function block _ET200S_SI08_send
● Function block _ET200S_SI32_send
The designation with ..._SIxx_... is retained in the following.
Note
The SIMOTION identifiers have changed as of V4.0. A comparison of the SIMOTION and
SIMATIC identifiers can be found in the Appendix SIMOTION and SIMATIC names
(Page 47) in the table "List of parameters".
The provided function blocks can be used to control one or more serial interfaced modules.
3.2

Function blocks _ET200S_SIxx_send

Task
The _ET200S_SIxx_send function block can be used to send data from the data send data
array to a communication partner. You have 1,024 bytes available for this.
