Micromod Micro-DCI: 53MC5000 PLC AND PRINTER INTERFACES - Manual (Page 41)

4.7 SET-UP PROCEDURE
The PLC documentation must be referenced to install and configure the PLC; however, examples
are given in this section of KF2 communication switch selections, initialization command selections
for the KF2, and KF3 initialization switch selections.
1. Reference the 53MC5000 Process Control Station book listed in the Preface to install the PCS.
2. See Section 2 of this book to mount the RS-232/485 ITB and cable connect it to the PCS.
3. This section provides an illustration of the required custom RS-232 cable if J1 of the ITB is to
be connected to the PLC; otherwise, the standard RS-485 four wire bundle can be used if TB2
is to be connected to the PLC. (PLC means the device in the PLC complex that is cable con-
nected to the PCS.)
4. See Section 2 of this book for the required power connections to the RS-232/485 ITB.
5. Define the PLC memory map as determined from the quantity of L-words and C-words to be
transferred between the PCS and PLC. The size and address locations of the PCS L- and C-
memory areas are defined in Section 3.1.
6. At the PCS and PLC, enter the appropriate configuration values as follows:
If PLC Network Connection to a KF2 or KF3
If there is a network connection to a KF3, see Table 4-6 for KF3 setup selections.
If there is a network connection to a KF2, see Figure 4-5 for KF2 Communication Op-
tion Switch Selections.
DF1 Protocol Selections
Typical DF1 protocol selections for the Initialization Set Variables command or DF1 pro-
tocol switch settings are as follows:
ACK Timeout - 01
Maximum number of NAKS - 01
Maximum number of ENQS - 00
DF1 protocol selections may require trial settings until operation is refined; for example,
two configurations (an SLC500 with a 1747-KE Communication Module and an SLC500
with a 1770-KF3 DH-485 Communication Module and 1747-AK Link Coupler) each re-
quired the following DF1 protocol settings:
Embedded Response Detect - ADER
ACK Timeout - 10
ENQuiry Retries - 00
NAK Received Retries - 00
PCS APB Setup Bytes (Table 4-2)
Mode (B290, B456) - 0 (to ensure interface is off.)
Baud Rate (B292, B458) - Set to match the PLC.
Set-Up (B293, B459) - Data format transfer protocol is set to match the PLC.
Self Address (B295, B461) - Use the assigned PCS address.
