 Process output data ( s. p. 138 )
Sub module "RS Data 24Byte IN/24Byte OUT"
The sub module "RS Data 24Byte IN/24Byte OUT" can be plugged into slots 2…9 (COM 0) and slot
11…18 (COM 1). The sub module is used to set up the transmit and receive buffer for the serial com-
munication via RS232 or RS485 modularly in steps of 24 bytes. The maximum length for the transmit
and receive buffer for one COM port is 8 × 24 bytes = 192 bytes.
This sub module can only be used for COM ports which are used as pure RS232 or RS485 interface.
 Parameters
This sub module requires no configuration and has thus no parameters.
