15.7 GP.ECPRTCL
(3) Functions
• The module specified by Un executes the protocol setting data written to the flash ROM.
The protocol is executed according to the control data of the device specified by (S) and the following
devices.
The connection specified by n1 is used.
• Protocols are executed consecutively for the number of times specified by n2 (up to eight protocols) by one
instruction.
• When two or more ECPRTCL instructions are executed simultaneously for the same connection, the
following instruction will be ignored until the first instruction is completed.
• The number of protocols is stored in (S)+0.
• Protocol execution status can be checked in the predefined protocol support function execution status check
area (address: 54C0
H
to 55FF
H
).
• The communication type of the protocol executed and fixed buffer setting of the connection No. specified by
n1 must be matched.
The following table lists the combination of the communication type and the connection No. that can be
specified by n1.
*1 To specify a connection where paring open is set, either of pairing-opened connections can be specified.
*2 When a pairing-opened connection is specified, an extra connection is used.
*3 When the protocols executed include the communication type of "Send&Receive" or "Send Only" and "Receive Only",
pairing open setting is required.
Communication type Connection No. that can be specified by n1
When the communication type of all protocols executed (up
to eight protocols) is "Send Only"
• A connection where "Send" is selected in the open setting
(no paring open setting)
• A connection where paring open is set
*1*2
When the communication type of all protocols executed (up
to eight protocols) is "Receive Only"
• A connection where "Receive" is selected in the open
setting (no paring open setting)
• A connection where paring open is set
*1*2
When the communication type of any protocol executed (up
to eight protocols) is "Send&Receive"
A connection where paring open is set
*1*3
When the communication types of protocols executed (up
to eight protocols) are "Send Only" and "Receive Only"
